Pat shrimp dry with a paper towel. Smash shrimp with the back of your knife and mince finely until you get a paste. (Or use a food processor to whip the shrimp).
1 pound shrimp
In a bowl, add minced shrimp, salt, white pepper, sugar, garlic, green onions, sesame seeds, egg white, and corn starch and mix until well incorporated.
½ teaspoon salt, Dash of white pepper, 1 teaspoon granulated sugar, 1 clove garlic, 1 green onions, 1 tablespoon sesame seeds, 1 egg white, 1 tablespoon cornstarch
Trim all the crust from white bread. Add one fourth of the shrimp paste to the bread and spread evenly. Cover with another piece of white bread. Use a butter knife to smooth the edges so shrimp doesn’t fall out. Repeat with remaining bread and shrimp paste.
8 pieces white bread
Brush or spray the top and bottom pieces of bread with oil. Air Fry at 375F for 6 mins on each side (12 mins total) without overcrowding (batch cook if needed). Serve with spicy mayo sauce. If deep frying, fry on each side for 2-3 mins until golden brown and shrimp is cooked through.
Oil, ½ cup Japanese mayo, 1 tablespoon sriracha, 2 teaspoon granulated sugar, ¼ teaspoon sesame oil, 2 teaspoon lemon juice, Pinch of salt
