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
- Eggs
- Thicken the dressing as they set with gentle heat, giving it body.
- Vinegar
- Provides the sharp acidity that defines the dressing and helps set the eggs.
- Flour
- Stabilises the mixture so it thickens smoothly without curdling.
- Sugar
- Adds sweetness to balance the sharpness of the vinegar.
The step that matters
Cook over low heat while stirring constantly. Egg proteins set at a fairly low temperature, so high heat or stopping the stirring can scramble the eggs into lumps before the dressing thickens evenly.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, egg, flour, pepper, sugar):
- Capsicumfits about as well
- Mustardthe original
- Shallotfits about as well
- Cucumberfits about as well
Fit is the average pairing score against vinegar, egg, flour, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
