Beef suet is the hard fat found around the loins and kidneys of cows, primarily used in traditional British cooking. It is a key ingredient for rich, flaky pastries and provides a depth of flavor to dishes like puddings, mincemeat, and savory fillings.
Given its high smoke point, beef suet is excellent for deep frying and roasting, rendering down without smoking excessively. When rendered, it produces tallow, which can also be used in making candles and soaps, showcasing its versatility in both culinary and craft applications.
