How to make smooth Chumus?
I like mine really smooth, so I make the whole thing in a food processor. You can use the "pulse" feature if you still want a little chunkiness, but if you want it really smooth, just process the heck out of it.

If you don't have a food processor, a blender may work too. If you have neither of those, you could try a very fine potato masher but that would be a lot of work.

For extra fanciness, I also like to top my serving bowl with a little pool of chilli oil to allow my guests to add spiciness if they wish.
