Shoutout to the old guy who told me to stop using metal bowls for my meringue
My first head chef in Chicago, a guy named Frank, saw me using a stainless steel bowl for egg whites and just shook his head. He said 'Use glass, kid. The fat in a metal bowl, even if you can't see it, will ruin your peaks.' I thought he was just being picky... but after three failed batches, I switched to a glass mixing bowl I had. The next meringue was perfect and held its shape for hours. Anyone else have a weird kitchen rule that turned out to be totally true?
