I found some recipes on allrecipes.com, and most called for this stuff called tahnini that I did not find in the grocery store (I did find an enormous tub of taheneh which may very well be the same thing, but since the recipe only called for a tablespoon or two, this was way too much), so I chose the recipe that was only canned garbanzos, olive oil, and a few spices. I mix everything together, dump it in my blender and get to stirrin'.
I learned that a blender made specifically for turning ice cubes into margaritas will make short work of a plastic spatula; only after, of course, I'm scooping my fresh hummus into a bowl, complete with shards of plastic.
The second attempt, however, went better. Too olivey, but still pretty good. Back to Giant for another $0.88 can of beans and another whirl.
