Marinate shrimp with egg white, salt, and Chinese cooking wine if using. Let sit for 10 minutes.
In a bowl, mix flour, cornstarch, and baking powder to create the coating mixture.
Coat each marinated shrimp evenly in the flour mixture, shaking off excess.
Heat vegetable oil to 350°F in a deep pan or fryer. Deep fry shrimp until golden and crispy, about 3-4 minutes. Drain on paper towels.
In a separate pan, combine water, bouillon cube, soy sauce, brown sugar, and honey. Heat over medium heat until bouillon dissolves.
Add the cornstarch water mixture to the sauce, stirring constantly until thickened and glossy.
Toss the crispy shrimp in the honey sauce until well coated.
Garnish with chopped green onions and toasted sesame seeds. Serve immediately.
