Mix the batter ingredients in a bowl - only 1/2 cup of flour, egg, baking powder, milk, salt and spices. Beat until smooth. The batter should drip slowly from the spoon.
Pour the remaining flour into a bowl and roll the shrimp in it. They can be with the shell on, the tail, or completely naked. Mix panko and coconut in a bowl. Now dip the shrimp in the batter so that they are completely covered or the tip of the tail is left clean.
Dip the shrimp in the coconut mixture until they are completely covered. Put the shrimp on a cutting board lined with parchment paper. Freeze for an hour.
Add the frying oil into your pan, enough for them to be submerged to heat up, about 3 inches. Heat to 350 F. In small batches (8-10 pieces), transfer the shrimp to the oil and fry for 6-7 minutes, stirring with a slotted spoon.
Cover a deep bowl with napkins and transfer the finished shrimp to them so that excess oil is absorbed.
