Tips:1 Tomatoes release a lot of water during the cooking process, so there is no need to add water when cooking tomatoes.
2 The tomato paste uses canned tomato paste instead of the usual tomato paste. If not, you can use it.
3 The ketchup does not need to be used up all at once, just take an appropriate amount.
4 Keep the remaining tomato sauce in the refrigerator and eat it as soon as possible.
