How To

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.

    I think you need to research and revise this advise. If you can find any way to use a wide mouth jar please test it and post. The video you cite is not credible, as some have commented. Try it and see what you think. Oster and others make blend and go containers, but I have been unable to find any safe, practical way to put a wide mouth jar on a blender of any brand. Would love to have an attachment and hope someone will craft one.

    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?

    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?
