I have heard stories from my parents and grandparents that my great-grandparents from Germany would save all types of animal fat (Goose, Pork, Beef etc) and use it for cooking and soap making. It was a precious commodity and was not thrown away. Also I think butter was pretty available. It wasn't until WW2 I think that it became scarce and vegetable oils and margarine came on the scene.
