I learned the BEST tip a couple of weeks ago and I keep forgetting to share. Do you ever boil-over on your stove? Pasta water? Oatmeal? Rice?
No more! Place a wooden spoon across the top of the pot and it will stop the liquid at the rim. In my attempt to multi-task, I tend to boil my pots overboard a LOT. Nothing annoys me more than oatmeal boiled over and baked onto my stovetop. Never again.
