Bulgur, also known as burghul, is whole wheat that has been parboiled, dried, and cracked. It is popular in Mediterranean cuisine. Bulgur is sifted into grades depending on the particle size. Since it has been parboiled, it is usually soaked or simmered for a few minutes to rehydrate before consumption. You can find the grain and lentils in most big supermarkets. You can also buy it from Middle Eastern stores and on Amazon.
