“When something spills or cooks over in your oven – just sprinkle salt immediately. When the oven is cool, use your pancake turner and pick up the burned pile of goop. Wipe with a damp sponge. Terrific!
I had scalloped potatoes boil over yesterday and what smoke and smell! I immediately grabbed my box of salts and poured it on the burned spill. Smoke died down, odors left, and I just kept cooking. After removing the food, I closed the oven door so that the heat would stay in the oven. Next morning, I just used my pancake turner and scraped up the awful mess.
I suggest that women should not try to clean up a mess like this when it happens. Close the oven door and let the heat finish your chores! There is always tomorrow…”
