家常炒菜人们一般只注意火候和调味不大注意用锅的科学许多人在炒完第一个菜后锅不洗净就加油炒第二个菜认为这样做既快捷又省事其实这样是很不科学的因为前一个菜的食物残渣在高温下焦化后会形成焦黑色的锅垢这不仅影响第二个菜的色香味而且还有害健康 Home cooking  people generally only pay attention to the heat and seasoning  do not pay attention to the science of using pot  Many people in the first dish after scald pot does not wash on the second fried stir fry food that is both quick and easy to do  In fact, this is very unscientific, because the food residue of the previous dish will form a scorched black pot after it is coked at a high temperature, which not only affects the color and flavor of the second dish, but also may be harmful to health
