To achieve a crispy exterior and tender interior, you must master the “double frying” technique:
First fry : Fry in oil at 60% heat (approximately 180°C) until cooked through and set.
Double frying : Quickly fry at 80% heat (about 200°C) to force out the oil, making the surface crispy and shiny.

Traditional sweet and sour sauce does not contain ketchup; instead, it is made with sugar, vinegar, soy sauce, and cooking wine. The classic ratio is:

The key is a balance of sweet and sour flavors and a glossy color, which can be adjusted to personal taste.
