“Everyone kept bacon grease in a can under the sink when I grew up.”
Mom had a can of bacon grease she kept on the back of the stove 24/7. Sometimes we used it on toast if we didn’t have butter. Grandpa kept one on his wood burning cook stove.
I confess that mine is in the fridge that I use for frying eggs.
I pour bacon grease into a shallow bowl (soup plate) that is lined with foil. Put it in freezer until hardened. Pop the disc of grease into zip lock in freezer.
When I want to add a little flavor, just break off a chunk to glaze on.
