Step 2, we add a proper amount of cooking oil to the pot. Let's have a look. This is a large iron pan, not a non-stick pan. Let's heat the oil to 70%.
3. 70% heat is when we see oil smoking all the time. Now we will shake the pan and spread the hot oil evenly around the pan. Ok, now we have to turn off the fire and let the oil temperature cool to 30%. What we just did was called baking pots in the kitchen. The advantage of this treatment is that no matter what you fry, it won't stick to the pot.
After the oil temperature drops to 30% heat, we turn on a small fire and then put in the freshly dried fish.
Now we turn it over, you can clearly see that the fish not only sticks to the pot, but also breaks its skin.
