2Mix coconut flakes and Panko breadcrumbs in a bowl and set aside.
3To make the batter, beat the egg and add flour, water, baking powder, paprika, salt, garlic powder, and black pepper. Stir to combine.
4Dredge each shrimp into the batter, then coat with the Panko/coconut mixture.
5Place coated shrimp on a tray and freeze for 10-15 minutes to prevent burning during frying.
