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 ↓

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 cook and bind it into a creamy emulsion.
- Corn starch
- Thickens the liquid as it heats, giving the dressing body.
- Sugar
- Adds sweetness to balance the sharpness of the vinegar.
- Vinegar
- Provides the acidity that gives the dressing its tang.
- Butter
- Adds richness and a smoother, rounder mouthfeel.
The step that matters
Cook over low heat until it thickens. Egg proteins and starch thicken as they heat, but high heat can scramble the eggs and leave lumps. Gentle heat with steady stirring keeps the dressing smooth.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, butter, corn, pepper, vinegar):
- Capsicumfits better
- Mustardthe original
- Asparagusfits about as well
- Potatofits about as well
Fit is the average pairing score against egg, sugar, butter, corn, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
