What is gutter oil?

Gutter oil is an oil made from kitchen waste such as leftovers, which contains a lot of bacteria and toxins. Once eaten, it will do great harm to the human body. In addition to hogwash fat, there is also a kind of gutter oil, which is the oil pulled from the gutter of the hotel. The use of these two oils has long been strictly prohibited by the food hygiene department, but in fact they frequently patronize our table and become "delicious" in your mouth and mine.
