In this recipe, I used a stainless steel pan It can take about 2-3 minutes to preheat on a gas stove or longer if you are using an electric stove.
Cooking time. I also reduced the cooking time to prevent overcooking for some users due to differences in the type of pan and stove they are using.
The cooking times will vary for a number of reasons. For example, a gas cooktop heats up more quickly than an electric one. For that reason, please check the doneness of the fish and adjust the cooking time accordingly to prevent undercooking, overcooking, and/or burning.
Non-stick pans. I do not recommend using a non-stick pan for searing crispy-skinned fish. The fish needs to be cooked in a preheated pan and non-stick pans will have serious problems (the coating will break down and start releasing toxic chemicals into the air) if you heat them without food in them.
If you decide to use a non-stick pan, you should start with a cold pan and heat it up with some oil in it. Please keep in mind that the final result of the fish won't be as crisp as it could be.
