When I was in my 20s my Mother gave me a light pink bowl she used for years. She passed it down to me when I had my own kitchen. I had the bowl in the refrigerator because there was a little bit of bread pudding left in it from the day before. I was being a bit lazy and did not put the leftovers in a Tupperware, you know how that goes. This morning I put the pink pyrex bowl on the stove to just warm a bit. I have never put it on the stove before. 20 years--never on the stove!
