Step 1Mix the mayonnaise and hot pepper sauce in a small bowl. Set aside.
Step 1Remove the shells from the shrimp, leaving the tails intact. Make a deep cut lengthwise down the back of each shrimp; wash out the sand vein. Add the salt to a bowl of warm water and stir to dissolve. Place the shrimp in the water and swirl. Let the shrimp stand 5 minutes, then rinse in cold water, drain and pat dry on paper towels. Sprinkle the shrimp with 1/4 teaspoon garlic salt.
Step 2Cut each spring roll wrapper into thirds, making 3 long narrow strips.
Step 3Peel the carrots and cut them into thin matchsticks 3 inches long. You'll need 24. Place the carrot strips in a small bowl, sprinkle with the remaining 1/4 teaspoon garlic salt, and set aside.
Step 4Brush some egg on the top of each shrimp. Place 2 carrot strips in the slit of each shrimp. Brush a spring roll wrapper strip with egg, then set a shrimp 1 inch from the end. Roll the shrimp up tightly in the spring roll strip, with the egg holding it together. The tail of the shrimp should be protruding from one end and the carrots from the other--to resemble a firecracker. Continue the process until all the wrappers are rolled with the shrimp and carrots.
Step 5In a wok or deep frying pan, heat the oil to 325 to 350 degrees. Fry the shrimp rolls until golden brown, about 2 minutes, turning 2 to 3 times. Drain them on paper towels. Serve with the dipping sauce.
