Trim tendrils off shrimp and rinse under cold running water. In a bowl, combine shrimp and garlic salt. Marinate for about 15 to 20 minutes. Drain shrimp and pat dry.

In a bowl, combine cornstarch, flour, pepper and 1 teaspoon of the salt. Dredge shrimp in cornstarch mixture until coated.

In a wide, deep pan over medium heat, heat about 2-inches oil to about 350 F. Add shrimps in batches and cook for about 2 to 3 minutes or until crisp and color changes. Remove from pan and drain on a colander. Reserve 2 tablespoons of the frying oil.

In a wide skillet over high heat, add the 2 tablespoons reserved oil and heat until smoking hot. Add remaining jalapenos, green onions and the remaining 1 teaspoon salt. Cook, stirring regularly, for about 30 seconds. Add deep-fried shrimps and toss for about 30-40 seconds. Serve hot.
