My spaghetti sauce is made with fresh tomatoes, ketchup, garlic, some vinegar, and some basic seasoning. I've been told it's not good to reheat the sauce over & over, but I'm making this for myself, 4 servings at a time, so the most reheats 1 batch would get is 3, and each batch lasts at most 2 days. I've been told to put the sauce in separate containers & only reheat 1 serving when ready to eat. I find it a pain to dirty extra containers and have had no problem reheating my sauce.
Is there some real problem with reheating my spaghetti sauce over & over, or is my family just too careful/concerned about it?
