If I don't have tahini is there anything similar to use to make hummus?
If you have sesame seeds on hand, grind some up. You could also use toasted sesame oil, and even combine it with the ground seeds.
You can also use all-natural peanut butter. Don't use mass market crap with sugar and other additives. The ingredients should list only: peanuts, salt. Obviously, this will taste like peanuts. It will still taste good in a hummus, but it will be a distinctly different hummus than with tahini.
Making tahini is quite a simple process, it's simply a combination of sesame seeds and olive oil. To make toast a quantity of sesame in the oven, on a moderate heat, for 5 to 10 minutes, but don't let them burn. Allow the to cool then, combine them in a food processor with olive oil. Add enough oil to reach the consistency you desire.
I loved hummus but then found out that I am allergic to sesame seeds. To substitute, I have used sunflower seed butter, almond butter or cashew butter. I have also tried combining a few of the nut butters for a more complex taste with good results. I have heard peanut butter works, but I am also allergic to peanuts so I cannot say much about it. Whatever you use as a substitute, make sure it does not contain a lot of ingredients, like sugar. My best substitute is to take raw, unsalted cashews and either soak them overnight or simmer them in water for about 20 minutes. The cashews will get really soft. Drain, then add 1:1 cashews and fresh water. Blend. The consistency will be very creamy like tahini. I know that what I make is not authentic hummus, but I still enjoy it.
I've used lentils with good results.
My kid is allergic to sesame, so I've tried different things and the best results where with some plain lentils.
It doesn't have the same tanginess but it definitely changes the flavor from chickpeas to hummus. Most of people don't seem to notice the difference, but I haven't tried with people that had been raised on hummus.
I cooked them with a bit of salt and them add 3 tablespoons, but I hold a bit on the water of the original recipe to correct for it and add a bit more olive oil.
