From my Pintrest board: This I will try and let you know how it turns out. The original blog post from Real Simple can be found here: http://www.realsimple.com/food-recipes/new-uses-for-old-things/you-need-blender-jar-10000000699904/index.html
It worked! You can use a Mason or Ball jar with the blender. My blender is an Oster, so I don't know if all benders work, but this did great. I tried several different sized jars, even down to a small jam jar size. This was something I originally saw on Pinterest on Swank Coffee's board.
Let me know what you have tried from pins on Pinterest that worked out for you.
