The principle of fast cooking with big fire

Meet the needs of the texture and shape of raw materials. The same raw material has different temperatures due to different textures and specifications. For example, tender raw materials should be heated quickly with strong fire to keep them tender; Tough raw materials are heated with medium fire or slight fire for a long time, so that their fiber tissue is loose and easy to chew and digest; The temperature of large, thick, long and thick raw materials is not easy to be introduced into the interior, and the heating time should be longer, otherwise it will not be cooked thoroughly; Small and thin, short and thin raw materials need shorter heating time and more firepower. Otherwise, it will make the finished dish too old or collapse.
