I am married to a tahini snob, there I said it. Rob is as into organic foods as the next vegan, but when it comes to tahini he kicks my organic jars to the curb. You have never seen a grown man throw a sulk like Rob sulks if we use some sub-par tahini. People have given us jars of their favorite tahini, but none of them stand up to his brand. We are known far and wide for our awesome hummus and maybe it is due to the tahini. He buys it in the 1/2 gallon jars, which, once empty, make great containers to store bulk foods in. Rob's tahini brand of choice is Ziyad. He is serious about tahini. Except no substitutes!
