Creating Salt and Pepper Crispy Shrimp is simple if you follow these steps closely:

1. Prep the Shrimp: Rinse the shrimp under cold water and pat them dry with paper towels.
2. Make the Coating: In a large bowl, combine the flour, cornstarch, salt, black pepper, garlic powder, onion powder, and cayenne pepper (if using).
3. Coat the Shrimp: Dredge each shrimp in the dry mixture, coating them evenly. Shake off any excess flour.
4. Heat the Oil: In a large skillet or frying pan, heat vegetable oil over medium-high heat until it shimmers.
5. Fry the Shrimp: Carefully add the shrimp to the hot oil in batches, avoiding overcrowding. Fry for 2-3 minutes on each side until golden brown and crispy.
6. Drain Excess Oil: Use a slotted spoon to remove the shrimp from the oil and transfer them to a plate lined with paper towels to absorb excess oil.
7. Sauté Green Onions: In the remaining oil, quickly sauté the green onions until fragrant, about 30 seconds.
8. Combine: Add the crispy shrimp back into the skillet with the sautéed green onions and toss to combine.
9. Optional Garnish: Sprinkle with sesame seeds for added flavor and presentation.
10. Serve Immediately: Place the crispy shrimp on a serving platter; it’s ready to enjoy!
