Here in Canada we can buy a spice mix called curry powder. I prefer to use it in place of the cumin. I have made hummus using sprouted garbanzos that I cooked and also using sprouted unhulled sesame seeds that I grind in a coffee grinder with a little oil before adding to the hummus. I recently discovered black sesame seeds in a Natural Health Food store run by an East Indian lady who has foods and spices that East Indians use. I also discovered a little black garbanzo bean called black channa which has a wonderful taste. So, between the black garbanzos which have a black skin and cream inside and the black sesame seeds it should be a very interesting hummus.
