Lately, I've been experimenting with fried stuff using a CI pan on the kettle.
I haven't tried fish yet, but I want to.
Heat the oil, then toss in the fish. For fish, I wouldn't let it go longer than 3-4 minutes, max 5.
There is no right way or wrong way. Your options are limitless.
This particular time, it was wings after being smoked for over an hour. Wanted to add some crisp.
