Recipe to make your own suet slabs or balls. Melt 1 cup of lard and 1 cup of peanut butter and then add 1/3 cup of sugar, 2 cups of instant oats, 2 cups cornstarch, 1 cup of flour and 1 cup of wild bird seed. Pour into a patty pan tray, or a baking tray and leave to cool and set. Your birds will be grateful!
