Brush the pot in advance.
Fuck (or fuck, absolutely.
No water
Or set fire to dry)
Put some oil in the bottom of the pot and fry the fish while it is hot.
(The more oil, the higher the oil temperature)
Then burn it, so it won't stick to the pan.
If your operation is too bad and sticky.
Just use this trick
Boil half a pot of oil and fry the fish so that you don't stick to the pot.
Note that the oil temperature should be 70% hot (over 200 degrees).
No matter how high)
And make sure the fish is dead in advance.
Otherwise the fish will jump into the oil pan.
You have to jump too.
This is all my personal experience.
Accept it.
