Tomato sauce
Your pantry may be stocked with tomato sauce you bought the last time there was a sale, but it always should go in the fridge after you open it. “In the old days, a lot of us used to keep tomato sauce in the pantry,” Lydia Buchtmann, spokeswoman for the Food Safety Information Council, said, “but since then these products have gotten a lot healthier, so they’ve got less unhealthy preservatives in them like salt.”
