1. Try not to cut the loofah into pieces. Many friends fried loofah black direct cause is the loofah cut into pieces, because many friends look at the hotel fried loofah, are cut into pieces. That's because the restaurant's fried loofah is fried directly in the pan, and the hotel's oil fried loofah is brightly colored but not watery. But don't cut it into chunks for the sake of our kitchen at home, because it's impossible to boil a pot of oil when the loofah is sauteed together, and cutting it into chunks means longer cooking time, which is the key to the blackening of the loofah. Just cut thick slices directly at home.
