When I was a kid, my family only bought the cheapest "butter" spread- Little more than colored grease i suppose.... and I beleived that "butter" was something you put on your food to make it cool down faster. It certainly didnt add any flavor! After I had real butter, I loved very hot food, so I could drench it in butter to cool it down faster.
