A soup base is a concentrated mixture used to enhance the flavor of soups and broths. It can come in various forms, including powders, pastes, or liquid concentrates. Common ingredients in soup bases include vegetables, meats, and spices, which provide depth and richness to the final dish. There are two main types of soup bases: stock and broth. Stock is made by simmering bones, while broth is made from meat and vegetables. Both can be used as a foundation for soups, stews, and sauces, making them essential components in many culinary traditions.
