Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they cook and help it set firm when chilled.
- Gelatin
- Sets the liquid mixture so it holds its shape when chilled and unmolded.
- Salmon
- Provides the main body and flavor of the custard.
- Milk
- Forms the liquid base that the egg yolks thicken into a custard.
- Vinegar
- Adds acidity that brightens the rich custard.
The step that matters
Cook the custard until thick. Egg yolks thicken only within a limited temperature range. Undercooked yolks leave the custard runny and unable to set, while overheating can make them curdle and turn grainy.
Swap the mustard
How well each one fits the dish's main ingredients (salmon, sugar, gelatin, egg, vinegar, milk):
- Cucumberfits better
- Capsicumfits about as well
- Asparagusfits about as well
- Mustardthe original
Fit is the average pairing score against salmon, sugar, gelatin, egg, vinegar, milk. Candidates are from the same food group and used in at least 100 recipes.
