Note 1: Here's what I do to dispose of bacon grease: Press 2 pieces of foil into a cereal-sized, heat-resistant bowl. Pour all the bacon grease from the skillet into this bowl. For this recipe, I measure out 1 tablespoon bacon grease and return it to the skillet along with the butter. I allow the rest of the bacon grease to harden at room temperature in the foil-lined bowl. Then either save that bacon grease or crumple the foil with the hardened grease in it and discard.
