Step 1

Drain the fish in a colander for 15 minutes and then pat dry with a paper towel.

Step 2

Mix the almond flour, protein powder and baking powder. Stir in the eggs and root beer or club soda. Let rest, uncovered, for 10 minutes. If it seems too thick, add a tablespoon or two of soda to thin it out a bit.

Step 3

Heat oil in the deep fryer to 350°F. Fry in batches to avoid the fish fillets touching. Dip each fillet, ensuring it is completely covered, allowing the excess to drip off and then carefully placing in the oil. Once the top is browned, flip the fillet and continue to fry until the thickest point reaches 145°F. Remove and drain on a paper towel.

Step 4

Serve with tartar sauce and a squeeze of lemon juice.
