Rendering beef fat for suet cakes and cones is a fun and simple activity for bird-watchers and nature lovers. Suet is a hard, whitish fat found around the kidneys and loins of beef or mutton that has a high melting point and so is perfect for making bird food. The melted suet is melted and mixed with other ingredients such as peanut butter, birdseed, and dried fruits to create a nutritious and tasty treat for feathered friends. Suet cakes and cones are a great way to bring different species of birds to your backyard, and they can be enjoyed year-round.
