To make basic suet, mix equal parts fat, such as shortening, and bird seed. Melt the fat until it is softened, and stir the birdseed into the softened fat. Place the mixture in the freezer to harden, and place the hardened suet in a mesh bag or suet cage outdoors. Optionally, add peanut butter, cornmeal, or fruit to basic suet.
Alternatively, melt 3 cups lard over low heat, and place 7 cups of birdseed in a bowl. Pour the melted lard over the birdseed, and mix the ingredients together. Pour the combined mixture into a foil-lined baking dish, and allow the mixture to cool. Cut the suet into six evenly-sized pieces.
To make suet with peanut butter, melt 1 cup peanut butter and 1 cup lard together, and combine 2 cups chick starter feed, 2 cups quick oats, 1 cup cornmeal and 1 cup flour in a bowl. Pour the melted lard mixture into the dry ingredients, and mix the ingredients together. Another option is to combine birdseed, oats or cornmeal with peanut butter, and place the mixture in holes drilled in a log or post.
Add chopped raisins, citron, dried apricots or currants to chosen suet recipe if desired, and store unused suet in the freezer until it is needed.
