Worcestershire sauce is frequently used to enhance food and drink recipes, including Welsh rarebit, Caesar salad, oysters Kirkpatrick, and deviled eggs. As both a background flavour and a source of umami (the savoury fifth flavour), it is now also added to dishes that historically did not contain it, such as chili con carne and beef stew. It is also used directly as a condiment on steaks, hamburgers, and other finished dishes, and to flavour cocktails such as the Bloody Mary and Caesar.
