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

What each ingredient does

Chicken breast or thigh: Provides the protein that browns and firms in the high-heat stir-fry.
Cornflour: Thickens the pineapple juice mixture into a glossy sauce when heated.
Tomato purée: Adds concentrated tomato flavour and body to the sauce.
Pineapple pieces: Adds sweetness and acidity that give the dish its sweet and sour character.
Pepper: Adds crisp texture and mild sweetness to the stir-fry.
Brown or white rice: Provides a starchy base that soaks up the sauce.

The step that matters

Thickening the sauce with cornflour. Cornflour must be fully stirred into cold juice before heating, then kept stirring as it heats. Starch granules swell and thicken only when hot, so stirring prevents lumps and ensures an even, glossy sauce.
