I found a recipe to make your own bird seed suet cake. It was easy and quick. The birds are loving it.
1 c lard
1 c crunchy peanut butter
2 c yellow cornmeal
1 c all purpose flour
1/3 c granulated sugar
1/2 c ground nuts
Mix all ingredients thoroughly.
Press into a sheet pan and chill.
Remove from sheet pan and cut into size to fit
your suet feeder.
