Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chicken pieces: Provide the main protein, which becomes tender during the long baking.
Hoisin sauce: Adds sweetness, savory depth and color to the marinade and glaze.
Lemon juice: Adds acidity that brightens the marinade and helps tenderize the chicken.
Cooked rice: Forms the base that soaks up the reserved marinade for moisture and flavor.
Onion: Builds a sweet, aromatic base for the marinade.

The step that matters

Refrigerate the chicken overnight in the marinade. The marinade needs many hours to penetrate the chicken, and turning the bag keeps every piece evenly coated so the flavor and tenderness are consistent.
