If you don't want to eat more times, that is, for too long, you can use a capacity of about 2 liters, that is, 4-5 kilograms of water; If you stew, pack and eat for a few more days, you can choose a bigger saucepan. Personally, I think it is better to have a bigger one, and the bigger one can be installed at will. If it is small, it is limited. If there is more than one person or several people, there is no way out. If all the pots and pans take up space.
