Place crawfish tails in a bowl and sprinkle with Creole seasonings, set aside.
Chop the shallots and jalapeno (if using), measure the remaining ingredients, set aside.
Make the Batter
Add the cornmeal, AP flour and spices; mix completely
Mix egg and buttermilk together and add to the dry ingredients; stir to combine thoroughly.
Add crawfish, corn, shallots, jalapeno (optional), stir to distribute evenly and combine thoroughly.
Let the fritter mixture sit in the bowl for about 15 minutes after mixing.
Fry the fritters
Place a cast-iron skillet over medium heat.
Heat about ½ inch of the oil to 350 degrees Fahrenheit.
In batches of about 4, use a ¼ cup measuring cup to add the fritter mixture to hot oil. See Notes
Gently flatten fritter with spatula before flipping.
Fry about 2 minutes on each side.
Remove the fritters to a rack over a paper towel-lined baking sheet.
Make sure oil returns to temperature before adding next batch.
Notes
Add about ½ inch of vegetable oil to the frying pan. The amount of oil this will take will depend on the size of the pan.Coat the inside of the measuring cup with a film of vegetable oil. This will make pouring the batter into the hot oil.Do not overcrowd the frying pan. Generally fry about 4 fritters of about 3 to 3 ½ inches in diameter per batch depending upon the size of the pan.I only recommend Louisiana Crawfish tails. Leftover tails from a crawfish boil are perfect for this recipe and will add additional flavor from the boil.Use frozen, canned (drained) or fresh corn.Leftovers should be stored in an airtight container. Fritters may be kept in the fridge for 3 to 5 days. Leftover fritters can be frozen for about 4 months. It’s best to wrap them individually in plastic wrap, then place them in an airtight container.
Allow them to defrost in the fridge overnight. For best results, reheat them at 350 degrees Fahrenheit for about 10 minutes or until they are warmed completely through. They can be reheated in the microwave but will not be as crispy.
