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

What each ingredient does

Chicken breasts: Provide the main protein, which turns firm and opaque as it cooks through.
Peppers: Add crisp texture and fresh, slightly sweet flavor when stir-fried briefly.
Brown sugar: Adds sweetness and helps the sauce caramelize and darken slightly.
Cornstarch: Thickens the sauce so it clings to the chicken and vegetables.
Honey mustard: Adds sweetness and tang that balance the savory soy and Worcestershire.
Lemon juice: Adds acidity that brightens the sauce and cuts through the sweetness.

The step that matters

Thickening the sauce with cornstarch. Cornstarch thickens only when the sauce heats enough to gelatinize its starch. Stirring the sauce in and cooking it for the full minute, with the pepper mixture returned, helps it thicken evenly and cling to the chicken rather than staying thin and watery.
