I first ate Tahini Sauce at a kebab and falafel restaurant when my fiddle teacher and I went out to lunch in Walnut Creek.
It has a distinct flavor: a slight bitterness almost but in a really good way! I could not stop eating it.
This version is from Jerusalem: A Cookbook, which is a really fun cookbook if you want to explore.
This tahini sauce should keep in the refrigerator for up to a week. If it gets too thick, just stir in a bit of water to thin it back down to the consistency you like.
Goes great on falafels along with tzatziki sauce.0
