1. Prep the Shrimp:
- If using buttermilk, place the shrimp in a bowl and cover with buttermilk. Let them soak for about 20-30 minutes in the refrigerator. This step is optional but helps in achieving a tender texture and adds flavor.
2. Prepare the Coating:
- In a large bowl, combine flour, cornmeal, Cajun seasoning, garlic powder, onion powder, salt, and pepper. Mix well to ensure even distribution of spices.
3. Heat the Oil:
- Fill a heavy-bottomed pot or deep fryer with vegetable oil, about 2-3 inches deep. Heat the oil to 350°F (175°C). You can check the temperature with a cooking thermometer or see if a small amount of flour sizzles when sprinkled into the oil.
4. Dredge the Shrimp:
- Remove the shrimp from the buttermilk and let the excess drip off. Dredge the shrimp in the flour mixture, making sure each piece is well-coated. Tap off any excess flour.
5. Fry the Shrimp:
- Fry the shrimp in batches to avoid overcrowding, which can lower the oil temperature and result in less crispy shrimp. Each batch should take about 2-3 minutes until the shrimp are golden brown and cooked through.
6. Drain:
- Use a slotted spoon to remove the shrimp from the oil and place them on a plate lined with paper towels to drain excess oil.
7. Prepare the Dipping Sauce (Optional):
- While the shrimp are frying, mix together mayonnaise, ketchup, Cajun seasoning, lemon juice, and hot sauce in a small bowl. Adjust the seasoning according to taste.
8. Serve:
- Serve the fried shrimp hot, accompanied by the dipping sauce and lemon wedges on the side.
Tips for Perfect Cajun Fried Shrimp:
- Shrimp Size: Using large shrimp helps keep them juicy during frying.
- Oil Temperature: Keeping the oil at the right temperature is crucial. If the temperature drops, wait for it to rise back to 350°F before adding the next batch.
- Seasoning: Adjust the amount of Cajun seasoning based on your spice preference. Cajun seasoning can be quite salty, so you might want to go easy on adding extra salt.
