I've always wanted a Magic Bullet blender, but I never wanted to pay for it. After reading several mixed reviews I never dropped the $50+ to pick one up.
If you've never seen one of the infomercials, it's essentially a blender system that comes with a bunch of different sized cups that you can make your shakes, salsa, or what have you, right in the cup. Instead of using a regular blender and dirtying both the blender carafe and the cup or bowl you're going to eat out of, you make it right in your glass.
Certainly a first world problem if I've ever heard one, but if you're making yourself a lot of protein shakes (check out my recommendation here) or making other supplements, you go through a lot of glasses and a lot of clean up.
So when I came across this little tip on Reddit a few weeks ago I was excited to go home and see if it would work with my blender. As it turns out, your everyday mason jar is the same size as most blender attachments.
For $.79 each I picked up a bunch of mason jars and now have an easy solution for thwarting double clean-up duty.
If you want to see if your blender will accommodate a mason jar before you go buy a bunch of 'em, the opening of a normal jar is about 2 5/8″.
This is also a great way to make properly measured, individual frozen drinks for guests like frozen margaritas or daiquiris. Or, do make-it-yourself milkshakes as a cheap date dessert and you can both customize your shake just the way you want.
The cap with the blades for the blender fits right on a typical mason jar. Note your blender may vary, they're not all the same size.
