How to Render Suet for Birds
Real suet, in its traditional form, is raw beef fat. Available at most butcher shops, the good stuff is super popular among nuthatches, chickadees and all woodpeckers, especially during the cold months. In fact, suet is one of the best foods for woodpeckers. Raw suet needs to be rendered. First, chop it into small pieces. (If you purchase it from a butcher, he or she may do this for you.) Next, heat the chopped fat on low until it’s completely melted. To remove potential contaminants, strain the liquid fat twice through a layer of cheesecloth. This also ensures that your cakes stick together and don’t crumble.

Good Ingredients for Suet
You can serve suet plain or put a little love into it and experiment with various bird-safe ingredients. Mix in unsalted nuts and seeds, fruits and berries, peanut butter and cornmeal until the consistency is a bit stiff. Some people even mix in dried mealworms and other insects to entice bluebirds! Once the mixture has cooled a bit, press into molds (try cat food or tuna cans, or form into your favorite shape) and refrigerate. Making your own suet involves a bit of trial and error. Depending on the ingredients you choose to mix in, you may need to experiment with the ratio of ingredients to avoid crumbly cakes.
“What’s your favorite suet recipe?” asks Diane Mlekush of McHenry, Illinois.
We actually haven’t settled on a favorite recipe, because we’re always experimenting with new ideas. But when we make suet, we always begin with equal parts lard and peanut butter, melting and mixing them over low heat. We add a variety of ingredients to this gooey mess: peanuts, raisins, rolled oats and cornmeal, to name just a few. Then we chill the mixture for a day before cutting it into blocks or cubes. When you offer birds homemade suet, check it regularly to be sure it isn’t moldy or rancid.

Can Birds Eat Bacon Grease?
Lard is a safe alternative to rendered beef fat. In fact, a combination of lard and peanut butter makes a nice base for any bird-friendly recipe. But bacon drippings are not recommended because the chemical preservatives in commercial bacon become more concentrated when cooked. This doesn’t pose a health threat to humans but can be harmful to birds.
