Why it works: Lettuce and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cheese Salad
Ingredients
Directions
Prepare the dressing
Grate the cheese finely.
In a bowl, combine salad oil and egg yolk; mix with a wooden spoon.
Add salt, pepper, mustard, and sugar; mix well.

Serve

Place a small heap of the cheese mixture in the center of each plate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and vinegar, helping the dressing hold together smoothly.
- Stale cheese
- Provides the main body and savory flavor of the salad.
- Salad oil
- Adds richness and carries flavor, helping the mixture stay smooth.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness.
- Mustard
- Adds sharp flavor and helps stabilize the emulsion.
The step that matters
Gradually add vinegar to the mixture.. Adding vinegar slowly lets the egg yolk and oil emulsify. Pouring it in all at once can break the mixture, leaving it greasy and separated.
Swap the lettuce
How well each one fits the dish's main ingredients (cheese, egg, vinegar, sugar, mustard, pepper):
- Capsicumfits better
- Horseradishfits about as well
- Lettucethe original
- Cucumberfits about as well
Fit is the average pairing score against cheese, egg, vinegar, sugar, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
