I never would have thought to use sesame oil instead of tahini. Is your sesame oil toasted? If it is, it seems like 3tbsp would give it an overwhelming sesame flavor. Not that that would be a bad thing...I love toasted sesame oil's flavor...just different from most hummus.
Also, thanks for mentioning Orna. I'll have to look it up and see if it's fun for me!
