Variations include suet made with peanut butter, cornmeal, breadcrumbs, graham cracker crumbs and quick-cooking oats. Some bird suet recipes call for raisins, coconut or peanuts.
Suet is made by mixing ingredients together and refrigerating until solid. Suet can be served on a tray feeder or hung from a tree branch. Suet can be made in advance and frozen until needed.
