Why it works: Mustard and vinegar 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 ↓

Ingredients
Directions
Poach the salmon

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and water into a thick, smooth sauce.
- Salad oil
- Provides the fat that gives the mayonnaise its rich body and texture.
- Prepared mustard
- Helps stabilise the emulsion so the sauce holds together.
- Vinegar
- Adds acidity that balances the richness of the oil and yolks.
The step that matters
Adding the oil. If the oil goes in too quickly or the mixture is not stirred fast enough, the emulsion breaks and the sauce turns oily and runny. Adding oil slowly while whisking lets tiny droplets disperse evenly and be held by the egg yolk proteins.
Swap the mustard
How well each one fits the dish's main ingredients (salmon, vinegar, egg):
- Cucumberfits better
- Chivefits about as well
- Asparagusfits about as well
- Mustardthe original
Fit is the average pairing score against salmon, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
