For best results, always follow package direction. When directions are not available, use this easy method:
 
 Combine 1 cup rice, liquid* (see chart below), 1 teaspoon salt (optional), and 1 tablespoon butter or margarine (optional) in a 2- to 3-quart saucepan. Heat to boiling; stir once or twice. Reduce heat; cover and simmer. Cook according to time specified on chart. If rice is not quite tender or liquid is not absorbed, replace lid and cook 2 to 4 minutes longer. Fluff with fork.
