Lamb suet is the raw, hard fat found around the loins and kidneys. Suet, as opposed to fat, contains a higher level of a triglyceride. The result is that suet has a higher melting point and solidifying point than regular fat. Goat Suet is used in many recipes, such as puddings, pastry, and sweet mincemeat. Goat suet adds a rich flavoring to almost any dish.
