Preheat oven to 300 degrees F.
Please proceed with much caution when frying foods in hot oil.
Add avocado oil to your deep cast iron skillet or dutch oven to be at least 1 inch deep. Avocado Oil
Turn heat to medium-low to slowly get it hot.
Each stove and amount of oil will vary with how long this will take. But a trick to see if your oil is hot enough is to dust some of the dry flour mixture to the surface of the oil. If it starts to fry, your oil is hot enough. If not, give it another minute or so and try again.
When the oil is hot enough, use metal tongs to carefully place a few pieces of fish into the oil.
Tongs are important so that you have control of the handling of the pieces of fish.
Cook for 3 minutes without disturbing the pieces of fish much. This helps set the coating.
Gently roll over the pieces of fish onto the other side
Cook for another 2-3 minutes.
(Keep in mind that if your pieces of fish are larger than the suggested size, they will take longer to cook.)
Carefully remove the hot fish with a slotted turner.
Place the fish on the wire rack over a sheet pan. (See photo instructions if needed.)
Fish should be cooked to an internal temperature of 145 degrees F, where it flakes easily but isn't dry.
Continue following the previous steps to cook all the pieces of fish.
Once all the fish is cooked and placed on the cookie drying rack/ sheet tray, place the tray with the fish on it into the warm oven.
Turn off the oven but continue to keep the fish warm in it while you prep the rest of the toppings. Or if your toppings are ready, you can skip placing the fish into the oven, and serve it up.
