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 ↓

Make the dressing base
Beat together vinegar, egg yolks, sugar, salt, mustard, and pepper in a bowl.
Pour the mixture into a saucepan and stir constantly over medium heat until it comes to a boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify and thicken the dressing as they cook with the acid.
- Vinegar
- Provides the sharp acidity that balances the richness of the dressing.
- Cream
- Adds richness and a smoother, softer texture to the finished dressing.
The step that matters
Stir constantly while heating. Egg yolks can scramble if they get too hot or heat unevenly. Constant stirring over medium heat keeps the mixture smooth and lets it thicken gently.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, egg, sugar, pepper, cream):
- Capsicumfits about as well
- Mustardthe original
- Horseradishfits about as well
- Spinachfits less well
Fit is the average pairing score against vinegar, egg, sugar, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
