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 ↓
Salad Dressing
Ingredients
Directions
Make the dressing
Beat the yolks of 8 eggs.
Add 1 cup sugar, 2 tablespoons mustard, 2 teaspoons salt, 1 teaspoon cayenne pepper, 1 pint vinegar, 1 cup butter, and 1 tablespoon cornstarch.
Mix the salt, pepper, sugar, mustard, and cornstarch together. Pour the mixture over the beaten yolks.
Let the vinegar and butter come to a boil, then pour them over the egg mixture and put all into a double boiler. Let it thicken.
Dilute the vinegar with water if it is too strong.
Serve
When the dressing is cold, use equal portions of whipped cream and dressing on salad.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the dressing as they cook and give it a rich, creamy body.
- Butter
- Adds fat for a smooth, rich texture and mouthfeel.
- Vinegar
- Provides the sharp acidity that balances the sweetness and richness.
- Sugar
- Adds sweetness to balance the acidity of the vinegar and mustard.
- Cornstarch
- Thickens the dressing as it heats, giving it body and stability.
- Mustard
- Adds sharp flavor and helps emulsify the dressing.
The step that matters
Let it thicken in the double boiler. Egg yolks can scramble if heated too quickly. Gentle, indirect heat in a double boiler lets the yolks and cornstarch thicken smoothly without curdling.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, vinegar, butter, egg, pepper):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Shallotfits less well
Fit is the average pairing score against sugar, vinegar, butter, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
