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 ↓

Ingredients
Directions
Prepare
Heat the water in a pot, but do not let it boil.
In a bowl, mix the pepper, salt, mustard, sugar, and flour with a little water to moisten.
Make the dressing
Add the eggs to the mixture and pour it slowly into the vinegar.
Cook the mixture over low heat until it thickens.
Thin the dressing with heavy cream to your desired consistency.

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 set, giving it body.
- Flour
- Helps thicken the dressing and stabilize it against curdling.
- Vinegar
- Adds acidity that gives the dressing its tangy flavor.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Heavy cream
- Adds fat and richness, softening the dressing's texture.
The step that matters
Cook the mixture over low heat until it thickens. Egg proteins set at moderate temperatures, and high heat can scramble the eggs and curdle the dressing. Gentle heat and steady stirring keep it smooth.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, pepper, sugar, flour, egg, cream):
- Capsicumfits about as well
- Mustardthe original
- Horseradishfits about as well
- Spinachfits about as well
Fit is the average pairing score against vinegar, pepper, sugar, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
