Why it works: Vinegar and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 20,806 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the liquid into a smooth sauce as it heats and gelatinizes.
- Sugar
- Adds sweetness and body to the sauce.
- Butter
- Adds fat for a richer flavor and smoother mouthfeel.
- Vinegar
- Adds acidity that brightens the sweetness and balances flavor.
- Nutmeg
- Adds warm aromatic flavor to the sauce.
The step that matters
Cook over low heat, stirring constantly. Cornstarch must be heated to gelatinize and thicken, but high heat or stopping the stirring can scorch the sugar and make lumps. Gentle, constant stirring gives a smooth, evenly thickened sauce.
Swap the nutmeg
How well each one fits the dish's main ingredients (vinegar, butter, sugar):
- Cinnamonfits better
- Tarragonfits better
- Peppermintfits about as well
- Nutmegthe original
Fit is the average pairing score against vinegar, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
