BlenderLadyBlog was correct.  I didn't know what I was missing when I only had the 64 oz wide bottom container.  I had trouble all the time trying to blend 1 cup of anything that didn't have enough liquid.  I'm not able to make hummus in my Vitamix, I could never do that before!  I'm still trying to perfect home made Nutella and nut butters, but it's so much better than my larger container.  I even got rid of my really old food processor!  Wish I knew this ages ago!
