Dip each shrimp into the batter and allow excess batter to drip off.
Fry the shrimp in batches until lightly golden and crisp, about 2–3 minutes per batch.
Transfer the shrimp immediately to a wire rack to drain.
Allow the shrimp to rest for 1 minute, then return them to the oil for 20 seconds to reinforce the crust.
Transfer back to the wire rack.
