It is recommended not to use naked fire, but to use electric cookers, induction cookers and the like. When cooking with an induction cooker, it is better to use a small fire at first, put oil in the pan after it is hot, and then pour the dishes into the pan immediately. If you are not good at cooking, an easier way is to buy a microwave oven, usually with recipes, which can directly microwave. There is nothing wrong with eating hot pot directly in winter.
