Have you ever hated trying to get the very last of the margarine or butter out of the tub? I have been doing this for years, but never thought to share it. When I make instant mashed spuds, corn, or anything that I want to enjoy with margarine, I sometimes find the tub is almost done with too little even for a spatula. So, I simply set it upside down on the top of the pan and let it melt. I get the last of it, and it's easier to wash and recycle. Hope this helps!
