Combine the dry ingredients. Add water and whisk well. Fill the fryer basin with 5 quarts (4.7 L) oil. Preheat the Wolf fryer module to 365°F. Meanwhile, prepare the shrimp and vegetables. Dry the seafood by spreading them out between layers of paper towels and patting completely dry. Immediately before adding the food to the fryer, dip it into the batter. Deep-fry 2–3 minutes, turning over as needed. Cool slightly before serving.
