How to stir-fry loofah without turning black?

1. Try not to cut the loofah into pieces. The direct reason why many friends turn the loofah black when they fry it is that the loofah is cut into pieces, because many friends see the loofah fried in restaurants and cut it into pieces. That's because the fried loofah in the restaurant is fried directly in the pot, while the loofah fried in oil in the hotel is bright in color but does not produce water. However, do not cut it into pieces for the sake of our home kitchen, because it is impossible to fry the luffa together and burn a pot of oil, and cutting it into pieces means that the cooking time will be extended, which is the key to the blackening of the luffa. Just cut into thick slices at home.
