Prepare the dough base: In a food chopper, mince the garlic. Add chicken thigh fillet, salt, sugar, chicken stock powder, oyster sauce, and pepper. Blend until the mixture becomes sticky to develop protein texture.
Add shrimp and other ingredients: Add cleaned shrimp, bread flour, cornstarch, baking powder, fried shallots, water, egg, sesame oil, and cooking oil to the mixture. Blend again until well combined but not too smooth. Refrigerate the dough to set.
Prepare cheese filling: Coat processed cheese spread pieces with cornstarch to prevent sticking. Cut into about 18-22 pieces. Shape each piece coated in cornstarch.
Shape shrimp and cheese mixture: Coat shrimp dough with cornstarch. Flatten it using plastic wrap to avoid mess. Place a piece of cheese in the center and fold the dough around it, shaping it into an elongated ball (similar to pastel shape). Coat hands with cornstarch to prevent sticking.
Steam for frozen storage (optional): Grease steamer with oil. Arrange shaped shrimp cheese pieces and steam on low heat for about 10 minutes with the lid slightly open to prevent cheese leakage.
Prepare wet coating: Mix medium protein wheat flour, salt, pepper, water, and egg until smooth to create a thick batter for coating.
Coat shrimp cheese pieces: Dip each shrimp cheese piece into the wet flour batter, then coat evenly with white bread crumbs.
Fry shrimp cheese: Heat oil to medium temperature. Fry coated shrimp cheese pieces until lightly golden brown. Drain excess oil.
Serve or store: Serve immediately or freeze for later use. If frozen and steamed beforehand, frying later reduces cheese leakage.
