Regular White Rice has been milled to remove the hull and bran coating. Regular white rice comes in long, medium and short grains. Long grained rice is the best for all purpose use. Brown rice has only the outer hull removed. The brown bran layer remains.
Brown rice has a pleasant nutty flavor and a firmer texture.
While white rice cooks in about 15 minutes, brown rice takes 45 to 50 minutes to cook. Precooked or Quick Cooking Rice has already been cooked and commercially dried. Cooking time is short. Parboiled or Converted Rice has been treated before milling to retain much of the natural nutrients. It takes 20 to 25 minutes to cook.
