Tip: Blender and Mason Jar

How to use a mason jar with your blender to whip or chop things right into the jar.

Did you know that many, if not most, blenders can be used with a standard mason jar, or wide-mouthed mason jar? This is a trick my mother taught me. Apparently 40 years ago or so, about the time this blender pictured was bought, manufacturers used to include a mason jar in the box with the blender. Mom recalls even a booklet that listed the many things one could make with the mason jar blender, including ground spices, whipped cream, and peanut butter. We use this trick most often to make whipped cream. The blender whips it right in the jar, so if we have extra, it’s already in a jar for storage. And it is easier when it comes to making small quantities.

I was complaining the other day that I needed a spice grinder. My mother reminded me of the mason jar trick and it worked perfectly. Here’s how to do it. I’m using walnuts to demonstrate, but you could use this trick with just about anything you want to blend, chop, or grind.

Tip: Blender and Mason Jar




Step 1: Remove the base from the regular blender container.


Step 2: Screw on the base to the mason jar. Make sure it is nice and tight.


Step 3: Invert the jar and place on the blender.


Step 4: Use as you would a food processor. Pulse or blend to desired degree.

    Be careful… Oster used to promote this idea but stopped after law suits.

    The actual blender beaker is made of tempered glass. Canning jars are not. A canning jar can have a crack. You try this with a cracked jar, especially with hot liquids, and cablooey!

    Despite this caveat, I personally DO use canning jars with my very old Oster blender.

    I guess I’m reviving this thread! I’m looking for a blender on eBay, which will work with wide mouth canning jars. It looks like yours does. Would you mind confirming that and if so, telling me what model Osterizer you have? The model number should be on the bottom. I prefer an older blender because I think they were made to last, unlike those made more recently. Thank you!

    I see that this is good for dry goods but what about to make smoothies. Are there any pressure issues with wet goods?

    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.

    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!
