1/2 cup lard
1/2 cup suet (usually found in the supermarket's frozen pies/pastry section)
1 cup peanut butter
1 cup flour
1 cup oats
1 cup cornmeal
hand full of birdseed (optional)
dried eggshells - roll them out with a rolling pin until they are like dust (optional)
Method:
Melt lard, suet and peanut butter in the microwave until soft and runny. Add remaining ingredients and let cool a bit. Before it's too solid, pour into molds or and place in suet holders - or - better yet put into a pine cone.
