Hello! Tahini is a thick paste made of ground sesame seeds and is added to Middle Eastern dishes like hummus. Tahini can be found in most large supermarkets and location will vary from store to store. Check the condiments aisle near specialty olives or in the ethnic foods department. If you can't locate it, ask your store representative for help -- they'll be happy to direct to the right location. Some smaller grocery stores may not carry this product. Good luck!
