Charcoal grilled fish have charcoal chips because of charcoal quality problems, grill problems, insufficient combustion, and ingredient problems:

1, charcoal quality problems: if the quality of the charcoal used is not good, the charcoal pieces may crack, crumble, and so on, which will lead to charcoal chips appearing on the food.

2, grill problem: If the grill used is not flat, the food may rub against the grill, which may cause charcoal chips on the surface of the grill to fall on the food.

3. Inadequate combustion: If the charcoal is not adequately burned, it will produce a lot of smoke and ash, which will cause charcoal chips to fall on the food.

4, the problem of ingredients: if the surface of the ingredients is not dry or have grease, the charcoal grill is easy to stick to the surface of the food, which will lead to charcoal chips appear on the food.
