Don’t reheat leftovers more than once. If you have a big pot of soup, for example, it’s better to take out what you need and reheat it in a smaller pan. Equally, the NHS recommends that you don’t refreeze leftovers. This is because the more times you cool and reheat food, the higher the risk of food poisoning. Bacteria can multiply when cooled too slowly or reheated insufficiently. Transfer food out of a hot pan, away from the heat source so that it’s not being kept warm through the residual heat.
