Sesame Tahini is a paste made from crushed sesame seeds and has quite a nutty taste. There are two main types of Tahini, Hulled and Unhulled.
Hulled Tahini does not grind the whole sesame seed and because of this it does not contain as much calcium, protein and vitamins as Unhulled. Unhulled Tahini is made from the whole sesame seed and it the most nutritionally packed type of tahini. You can use Brown or Black Whole Sesame Seeds. Hulled Tahini is not as bitter tasting as the Unhulled type. Raw Tahini contains more nutrients than roasted tahini.
A basic recipe for Tahini is to grind 1 cup Sesame Seeds in a blender or food processor. Slowly add ¼ to ½ cup oil (Sesame, Olive, Peanut and other oils are used). This will make a thick paste to which you can add garlic, salt, lemon juice and / or buttermilk to achieve desired taste and consistency.
