    wow – way cool. aside from the obvious capacity issues, is there anything that would work in a blender that *wouldn’t* work in a mason jar?

  2. Elise

    Hi Kathryn, thanks for your kind words! (We like lots of love here.)

    Hi Jen – Hmmm. Don’t know what wouldn’t work in a mason jar. The regular blender jar is more convenient for measuring and for adding ingredients from the top.

    Hi Grommie – don’t all canning jars come in standard sizes?

    Hi Chrzpiz – good to know that the Osterizer company is still keeping up this useful practice.

    Hi Matt and Jennifer – you are very welcome!

  3. Elise

    Hi Easy – Caught! Yep, that would be me. LMT started because I needed to have a place to keep notes of how I did things on the recipe site in Movable Type, starting with the three-column layout. Glad you found it useful, if only for a while.

  4. Mad William Flint

    Be very careful when doing this. Liquids (esp hot soups, etc.) can cause strange pressure changes in a blender and would, at best, make a mess if you used a glass jar.

    Common sense and all that ;)

  5. aardvarknav

    I suspect that it could get very interesting using the closed Mason jar with hot liquids. Might be like the rocket toy we had as kids that you put water in and then pumped air into it.

  6. Amy V.

    Wow! This is great! It seems to work much better than the regular blender for grinding dry things. I ground up some oats into powder, and it was much easier than in the regular blender jar. I didn’t have to keep shaking it to dislodge unground bits from the sides.

    Although, I have discovered that apparently there ARE non-standard size Mason Jars, and most of mine are these. I found one that actually said “Mason” and it fit just fine on my Cuisinart blender.

  7. Anonymous

    Very cool. I will check to see if the cuttin attachment will fit smallest size of jars, which would be excellent for grinding spices. As far as fit goes, be mindful that there are two sizes of Mason jars–normal and wide, and from the fotos, it looks like the normal size. -JBF

  8. Elise

    Hi JBF – yes, which sized mason jar you use depends on your blender. My osterizer uses a normal size mason jar. My friend’s Kitchenaid blender fits a wide-mouthed mason jar.

    Apparently you can use a mayonnaise jar too, in place of a normal sized mason jar.

  9. Sue

    What a great idea!
    My problem is that the base is stuck to the
    blender and I can’t get it off.
    Any tips on how to separate the units?

  10. Eric

    Awesome idea! I hate always having to stop and wash the blender when i have to make alot of different stuff. Problem solved! And if you have a blender that uses the regular mouth, you can get “mason mugs” from ball (mason jar with a mug style handle) for frozen drinks right in the mug. Saves dishes…

  11. Scott

    What a great tip! Combine this with a Foodsaver and you can have ground spices that last forever. I was also thinking of the mason mugs too, but someone beat me to it. Thanks!

  12. Anna

    I have been doing this for years. May I add two more hints, in addition to the caution about avoiding too-hot liquids:

    Sometimes a round jar is not quite as efficient as one with a square shape (rounded square, that is).

    Check the jar for cracks and flaws before using it. I used to use a Mason jar for grinding coffee, until the day it broke during the grind and scattered coffee grounds and bits of glass all over the kitchen.

  13. Robin

    I have a separate coffee grinder set aside (no coffee has ever touched it) for spices. I quite buying ground spices years ago and now get all my spices whole at the Indian grocery store down the block.

    This is a great tip! I hope it works on my blender. I had a blender that has a “mini-cup” for this purpose but I killed it making smoothies w/ too much ice. Careful when doing this since you can’t stir the ingredients you have to watch carefully for stuck blades and dry-running!

  14. Bob

    I just tried this, and the gasket does not get compressed because you can’t screw the base down far enough. If you try this trick, fill the jar with water first, it’s easier to clean up than peanut butter.

  15. Anonymous

    Was searching for Mason Jars to order and found this. Our preserving jars fit our Oster blender. Now we can get rid of our coffee grinder. This is just a great tip, and something we may never have thought of on our own.

    Thanks a lot!

  16. LaVonne Ellis

    Great tip, thanks! I just tried a Mason jar on my Cuisinart blender for size and it fits perfectly. I use a coffee grinder to grind roasted sesame seeds, but it never cleans up enough to use for anything else. The sesame flavor would get into other spices because I can’t wash the grinder, only brush it. Also, I definitely plan to get some Mason ‘mugs’ for smoothies!

  17. Jon Tyson

    That also solves the problem of getting stuff stuck at the bottom of the blender. When the jar it attached you can just take it off and shake it, rather than trying to dig around with a knife.

  18. Jill

    Thanks for the wonderful tip (reminder)! About 15 years ago (is it that long ago?), I bought a Oster blender and it included a smaller jar with which I made purees and things. I completely forgot about that. It’s wonderful to know that any wide-mouth jars also work.
    -Jill-
    P.S. I love your blog! Thanks for sharing wonderful ideas and delicious recipes.

  19. Elise

    Hi Jill – Whether you use wide mouth or regular depends on the blender. The old blender pictured here uses a regular jar. Our new Kitchenaid blender uses a wide mouth jar.

  20. Amy

    This is a really awesome tip. I don’t have a mason jar but would any glass jar work as long as it fits the blender base? Does the glass have to be a certain thickness? Would this technique work for small amounts of spices (a teaspoon or two)? I’m afraid it would collect at the bottom of the jar as the blade spins around.

  21. Karen

    I have a blender exactly as shown in this
    Tip: Blender and Mason Jar
    I bought it at a garage sale recently and it works great, as in the motor etc., but the glass jar is stuck to the base. I do not know what to do to get it apart to clean it and to replace the rubber seal. Could I use WD-40? Please help.
    Thanks everyone
    Karen

  22. Susan

    Get out of Dodge. I used the small Hellman’s mayonnaise jar & it worked like a charm. Then I just store whatever’s leftover right in the jar. The empty jar & lid go right into the dishwasher for my next recipe. I’m already using this trick to make a million things. I picked up some Mason mugs for smoothies. I no longer have to dirty the entire blender jar. I can make the smoothies right in the mugs. When it’s hot outside, my husband & I love them instead of coffee in the morning. Thanks so much for these invaluable tips.

    Also, I made the peach/blueberry cake & followed your instructions to cook it longer & grease the pan. Your suggestions were right on. That cake is absolutely out of this world. I will be making it again & again for my family & for company.

  23. Lexy

    I came across your web page, looking for something to do with all these jars I’ve saved (for a rainy day or something), and I am speechlessly amazed at your discovery!!! My blender is a Hamilton Beach, though, but it looks like it will work just fine. Thank you, thank you, thank you for the idea!

  24. Smo

    Karen: You might try submerging it in hot water for a while (the base and jar, sans blender of course). That could make the plastic/metal in the base expand a little, without expanding the glass.

    Then just get one of those nice lid-removers if you don’t have one, and maybe a friend with strong hands, and go at it.

  25. Michael P. Powers

    Hi! I was wondering if it is possible to use the mason jars with handles for canning? If not where might I get some, if anywhere?
    Thank You Very Much,
    Michael P. Powers

  26. tom

    Remember sometimes these recycled jars (from Mayo etc) are thin glass and not tempered and could break with hard items such as spices/ice etc. That is why some manufactures recommend not using recycled jars for canning etc. Just be careful.

  27. HM

    Would you believe that I just had to get up and try this for myself? I just happened to have a mini mason jar because we had some pasta with Classico pesto sauce. How incredibly cool!

  28. David

    This is a great tip.

    The thoughts about hot foods are definitely a warning. Anytime I blend something hot, the lid of the blender practically blows off because the steam released is 7 times the volume of the liquid that created it. So, I’d stay away from trying to blend things in a sealed jar that are steaming hot.

    Also, I would definitely use only real canning jars (Ball, Mason, etc.) because they are a stronger glass, made to withstand the higher temps of canning, than old mayo jars. Yes, the mayo jars do fit, but they are definitely thinner glass, so they will shatter more easily when trying to grind things like coffee beans.

    I would NOT want to try this with something like hummus, where it is very thick. Maybe even peanut butter. The jars MAY not have the high amount of sticking that the strangely shaped blender container has, so it may not be such an issue. I’ll probably try it once. But, if I have to scrape down the sides, then I’ll go back to the blender container because one can scrape down the sides of that while the blender is running.

    We once ground whole cloves in our coffee grinder & then transferred them to a separate bottle. There was enough clove powder (barely any) in the air that my wife got a case of hives. We’ve never done that again. But, with this, it may work just fine, & I can take the bottle & blender base outside to open it up & put the cap on the jar, without getting the miniscule amount of clove powder dispersed into the inside air.

    GREAT tip!

  29. susan

    What a great idea, just makes you wonder what other neat ideas people used to know that we have all forgotten or were never told. I have a friend that was going to buy a electric coffee grinder to grind up flax seeds, but I will tell her to save her money! Thanks.

  30. Mary

    I agree this is a great tip I’ll try tonight.

    One word about grinding flax seeds – they go rancid right away – it’s best to grind flax just as you use them.

  31. Reid

    I’ve been doing this for about 20 years. One word of advice:

    DON’T USE MAYONNAISE JARS!!!! They fit, but they are dangerous. The glass is thin and I had one send me to the hospital for 4 stitches when I was grinding up some dried out palm sugar for Thai cooking. The jar exploded. BANG!!!

    Also don’t use mayonnaise jars for hot food. They aren’t tempered. I had a friend that got 6 stitches in his pinkie finger when a 1 gallon jar broke when he placed it on the counter.

    Just recycle mayonnaise jars is the best thing to do with them. A case of Ball jars is so cheap anyway

  32. Jamie

    HI;
    I love the idea of using the jars with my oster. I will definitely try it.

    I ran into a problem with my oster today with my regular blender jar, I thought I had it on there tight, and when I was blending, it came unthreaded, and the full jar popped off, dumping all 5 cups of my protein shake everywhere! What a mess! I suspect I might need new seals for my blender jar or something.

  33. Rob Lewis

    My old Hamilton Beach blender came with a set of “mini-blend” containers in different sizes for doing this. They’re made of some hard, tough plastic and include screw-on plastic lids for storage. IIRC, the directions said it was OK to use Mason Jars, but don’t use thin jars like mayonnaise jars as they may break or explode.

  34. Jenny (usagi)

    I heard this trick somewhere else a while ago, sadly after I’d already bought one blend & go mug for my Oster Fusion. They fit perfectly and I love using them for making smoothies and drinks and the like.

    I also found out the Safeway spaghetti sauce jars (I don’t recall the exact ones) are large mason jars. So those get washed and reused for this also.

  35. AngelSong

    Hi, Elise,

    What a great tip! This is going to save so much aggravation. I never miss your updates. Thanks for sharing so many wonderful recipes, stories, and tips.

  36. annie

    Awesome! I have a blender that doesn’t have a lid (long story) Should have thrown it away a long time ago, but I guess I was waiting to read this!

  37. LaVonne Ellis

    I have a feeling this is one of your most popular posts, Elise. I just came across it while looking for Mason jars and remembered reading it a long time ago. Reading the comments, I saw one that made me think, “I do that too!” And then I realized I wrote that comment, heh. I still have to get some mugs and make smoothies.

  38. Glitterati

    This is so clever!! I can’t wait to try it out, thanks for sharing Elise!

    A tip for blending hot liquids in a regular blender: start the blender dry, then add the hot liquid in by the spoonful. No explosions this way, even though you’ve got the lid off. (I wouldn’t try this w/ the jars though, just use the regular blender pitcher)

  39. Foodaholic

    That’s awesome! I have a blender, but always use a magic bullet when I want to blend a small quantity. It’s not really great. This, I’m sure will be much better. Thanks!

  40. Pam

    The best part of this is that glass jars aren’t made of plastic BPA–which is in all the Magic Bullet type machines. So, in addition to the already stated benefits–you also get a BPA-free smoothie! Great!

  41. j

    Be sure to pick a few more sealing rings. We had the tendency to over-tighten the jar to the base and ripped the sealing ring.

    Just a thought.

  42. annakita

    Life is truly full of surprises. This is like unexpectedly coming upon a treasure chest and finding a priceless gem inside!
    I struggled to see if my blender would work. It wouldn’t unscrew. After reading comments here and at other sites, and making several more attempts, I was left wondering if this gem was really meant for me. Then I pulled up my blender guide/manual, and, yes, it’s screw-type! With determination I returned to the kitchen and it unscrewed!
    My first use resulted in a wish come true. In my youth “bar sugar” was easy to find in supermarkets. When appropriate, it’s perfect for so many uses. It’s superfine (also known as caster/castor sugar) and, therefore, easy melting to blend drinks. It’s perfect to make cold drinks like lemonade and iced tea. My supermarket carries a small, pretty, cellophane-wrapped package of caster sugar for about $5-6.
    Making it myself seemed too much trouble.
    Well. Half a mason jar filled with regular sugar, my blender, and me – Wow! – bring on the iced tea and lemonade!
    This gem is mine, and I can’t wait to share!

  43. Lesley

    Wonderful! Vaguely familiar, too, as if I heard of it, in passing, when I was a child.

    Ideas: For jars too short-necked to screw the blender ring on all the way, maybe try adding more seals (flat rubber rings) to fill the gap. Careful, though: There will be more stress (risk of breakage) on the jar’s neck.

    In which case, maybe the newer plastic mayonaise jars will work. Plastic isn’t so fragile.

    Now, I just need to buy a blender. A friend has recommended the Magic Bullet Blender, even though hers had burned out, so I was researching it, and then other “personal blenders” because the MBB is expensive, too, when I found your website. Problems solved!

    One other thing: I’m an RV “fulltimer”, with no space to waste. The MBB is small, but the regular blender base isn’t much bigger, and I don’t have to store accessories I don’t need. Replacement parts are much easier to find and less expenive for a regular blender, too.

    Thanks you!!!!

    Lesley

  44. Bev

    Wonderful idea! Just made two smoothies using a 16oz Mason Jar and my old Oster blender….worked perfectly. Will save more jars to use for spices, salad dressings and of course, more smoothies.

    Thank you to you and your mother! Now to go find some of those mason jar mugs:-))

  45. Lesley

    Following up, I decided to shop Wal-Mart, where I could find jars and blenders, and see which fit what before buying. Oster (for only $25) fit Mason regular-mouth jars. Kerr was the only other brand of jar there, and its regular size has the same fit.

    When I got home and tried it out, turning watermelon to juice-in-a-jar was no problem. I wasn’t sure how full to fill the jar, safely, so I settled for 60-75%. If you have any details on this, please share. The information insert that came with the blender didn’t mention canning jars, but it did refer to an 8 oz. “Mini-Blend Jar Accessory.”

    There was a problem when I tried to convert a jar of green olive and pimento pieces into a Mason jar of pureed olive spread. The gasket kept getting wound up into the blender blade. I think it had something to do with the high content of olive oil present, greasing up the parts, so to speak. The gasket was impressive, though, showing almost no sign of damage, and still functioning fine, after the 3rd try.

    Lesley

  46. al

    Great advice, can’t wait to try it! Question, does anyone know if other jars besides the canning type would work if one doesn’t have a way to get them right away? Since glass jars may shatter, can plain plastic jars be used temporarily, or is that dangerous? Does this tip work on all types of blenders (Hamilton, Oster, wave type, etc.)? Thanks.

  47. Adam

    I Use the oster and a mason jar on steamed carrots for babyfood. Brilliant. Saves the awkward spatula work if I use the full sized mixing jar. I’m waiting to try this on the next batch of fresh herbs/spices to come my way.

  48. michelle

    Canning Jars are the greatest thing!
    I was so excited when stumbling on this tip today! Just another reason to have my cupboards loaded with the jars! And yes! I had to go try it right away!

    A further note on the jars. Because canning jars are made of the tempered glass, they deem to be heavy duty–compared to even most drinking glasses.

    In our home, jelly jars are juice glasses, pint and quart jars (for hot & thirsty days) are used for regular drinking glasses. At prices up to $7 for a dozen pint jars– (cheaper or free if you find them on yard sales and freecycle!!)– you can afford to have a broken glass periodically!

    I also use the canning jars, of all sizes, for storage in my kitchen for dry foods, dehydrated foods, and in my craft/office for many different supplies!

    Kudos!

  49. al

    Hi,
    Great advice! Does anyone know what type of Mason or other jar will fit a Wave Logic blender? They have an odd base, regular Mason jars don’t seem to fit. A jar will make it easier to blend small quantities. Thanks!

  50. Shaker

    I have been struggling for a few years now, with the problem of being unable to blend small quantities of Indian chutney with a blender. (I usually cook for one person.) I was very happy to see your tip. My Mason jars fit perfectly in the blender. My chutney still didn’t blend evenly but a big step forward though. Thanks.

  51. cindy f

    This is so fantastic! I’ve been coveting the ease of use of the magic bullet and its ability to make smoothies to go, but didnt like the plastic cups. An internet search came up with zilch for a glass jar made by the manufacturers.

    Thank you for posting this!

    I’ve tried my jars of pasta sauce (says mason on the side) and voila!! They fit!

    Yay! One less single use appliance in the kitchen!

  52. Deli

    Elise, it’s coming up on the 5 year anniversary of your enlightening post, and you’re still changing people’s lives after all these years! I’m high-5ing you in the ether for your most brilliant tip that thrills me to no end! I now grind my flax seeds, oats, walnuts and dried fruits for granola in Mason jars and mugs with great ease and joy… THANK YOU!!!

  53. T-Cee

    Just came across your blog (very cool) and saw this mason jar tip. I’ve GOT to run out and get a mason jar to check this out. I HATE cleaning out the blender for small quantities of food prep and my mini prep – well I think the blades are dull – it doesn’t seem to work as well as it used to.
    Thanks.
    T-Cee

  54. Sara

    Thanks. I had completely forgotten about this trick. I even have nice jars with handles & lids that I bought for this purpose but they were tucked away in a cupboard. You saved me from buying a new grinder. Thanks!

  55. erin

    Thank you!! This is yet another example of commonplace ideas which have been lost over the generations. I relish them. Simple and thrifty solutions, and usually very good ideas for clean and non-toxic living…another thing that has been lost by the masses. I am going to use this as a solution for making babyfood out of my own homecooked organic meats and produce. yay!

  56. John

    My wife was making us smoothies in her old blender with a glass container. She has done this many times in the past; but this time, much to our surprise. the glass jar broke and smoothie and glass went all over the kitchen. Luckily no one was hurt;but it took 3 hours to clean up the mess because it went everywhere!! Made me very leery of glass containers on a blender. It was the original blender container that came with the machine.

  57. Lynn

    Last year on April 8, I was using my Oster blender and a pint canning jar to make natural peanut butter smoother. Before I could hold the jar down after turning the blender on, the jar came unscrewed and the blade became air born chopping three fingers on my right hand. After emergency surgery and months of therapy, I can see that I have permanent damage. Please DO NOT use jars on a blender that operates in a counterclockwise direction. I have used jars on blenders since the 70′s and this was the first time I had this happen. I do have to say when I used the Oster container, I also noticed a leakage when blending liquids but I did not realize the direction the blade was turning causing it to leak.

  58. Wyatt

    What an amazingly clever idea! This article supposes that most modern blenders use the same-sized mouth as the ones from 40 years ago though, correct? Any idea if blenders are still made with a mouth roughly the same size? Also, seems like it could be messy when the time comes to flip the unit over and remove the mason jar (with blended, pureed, and whipped contents within!).

    But I love the creative concept, and if I ever lose my glass food processor unit, I now know what I will try before buying a new one! Bookmarked for sure! :D

  59. aileen mackanzie

    I love your out of the box thinking. And the mason jar idea actually solves a couple of my kitchen problems. Thank you.

  60. Ryan

    hmm, I’m having a hard time finding a reason why using a Mason jar as opposed to a blender would be any different, or any more beneficial, other than the fact that stuff like peanut butter would stick to the blender, whereas with the Mason jar, no transfer is needed.

    Is that it? What would be so different about chopping nuts using a Mason jar?

    I’m just curious, because I don’t really cook, or prepare food at all. However, this just looks a little gimmicky to me. Is there a big difference, and if so, what is it?

    Sometimes getting things out of a blender can be tricky. This is just an easy way to chop or blend something, and then have it already in the container you intend to use to store the item. Also, sometimes it’s actually easier to use the mason jar for chopping things like nuts. Probably because in the mason jar, the nuts have a smaller place in which to fly around, and therefore you will likely end up with fewer big, un-chopped nut pieces. ~Elise

  61. Steve

    I would be very careful about using this tip. The blender container is made to contain the pressure and vibration created by the blender; mason jars aren’t. And the cheaper, or thinner the jar, the more easily it will break. If the mason jar broke, you could have glass fragments coming out in a 360 degree arc. Is it really worth it? Funnels for filling mason jars are a couple of bucks. If you really want to do this, buy a jar made by the blender manufacturer; don’t just stick some mayonnaise jar made by the lowest bidder, thinned out as much as possible to save on shipping weight.

    If you don’t want to believe me, at least send the kids out of the room before you try it.

    Hi Steve – you should know that 1) mason jars are made with extra strong glass, to handle the heat and pressure that comes from home canning, and 2) using a mason jar this way with a blender was normal years ago. The blenders even came boxed with a mason jar and a booklet of instructions of how to use the mason jar with the blender. ~Elise

  62. Ann

    I just went to Walmart to buy a cheap 24.00 Oster blender 14 speed. I tested the Ball small mouth jars with it and it worked so I bought pint sized ones. This is the best thing ever. I’m going to buy different sized Kerr Ball canning jars with the small mouth lid for my baby food.

  63. Veronique

    Darn you black &decker! My ridiculously fancy blender/food processor machine doesn’t work. The normal mouth can’t fit the blade in by about a quarter inch, and the wide mouth wouldn’t screw cause it’s too big! Grrrrr! Doesn’t it makes you mad to know that there was a time when durability efficiency and practicality were standards? Now my couple of hundreds $ machine doesn’t do what a cheap wall mart machine can do… And I thought it was so cool that I needed only one base for the two machines! I think I will write to the company…

  64. Sierra Bufe

    This is in response to Lynn on April 12, 2011 11:05 AM.

    I checked my Oster setup with respect to the counterclockwise question. I can see which way the blade is going from the shape of the edges. It does go counterclockwise.

    The jar or pitcher receives the blade assembly while you are holding it upside down, and you screw that on clockwise. However, when you turn the container upright, the direction of tightening becomes counterclockwise. The counterclockwise spinning is designed to tighten the screwed on assembly, not loosen it.

    Lynn, I’m so sorry for your accident. That sounds really terrifying. I think it’s good to share that we all need to treat these machines with respect, because it’s always possible for something to go wrong.

    Elise, thanks for this post! Awesome work!

  65. Sierra Bufe

    One other thought I had — it’s possible that some of these incidents where the jars or containers seem to immediately come loose could be the result of a quick cross-threading. You stop twisting because you feel resistance, but there’s really no security to the attachment at all.

    Every time I put it together, I plan to take it slow and make certain I’m not cross threading the assembly.
