Onion is a basic flavoring in the kitchen. It is used as a vegetable, or as a spice to bring out the flavor of other dishes without overpowering them. It often accompanies meat, especially mince and meat dishes such as shepherds pie and meat loaf. Onion is also widely used in soups, pickles, and cooked vegetables, sauces, hearty casseroles, and bean and lentil dishes. It is also a common ingredient in marinades. So whether it is soup, stew, stir-fry, salad, or sauce, chances are that the recipe includes onions.
