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 ↓
Salad Without Meats
Ingredients
Directions
Prepare the salad
Separate and wash the lettuce leaves thoroughly.
Soak the lettuce leaves in cold water to crisp.
Wipe the lettuce dry and spread it out on a flat dish.
Peel and slice the tomatoes and cucumber thinly, layering them over the lettuce.
Add onion if desired.
Make the dressing
Cook the yolk of one egg in a bowl, stirring constantly to make a smooth paste.
Let the cooked yolk cool.
Stir in the two raw egg yolks, mustard, salt, and sugar to taste.
Add olive oil and the juice of one lemon to the mixture, stirring well.
Serve
Just before serving, pour the dressing over the salad.
Slice a lemon over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify with the oil and lemon juice to give the dressing a smooth, creamy body.
- Olive oil
- Adds fat and richness, carrying flavour and giving the dressing a silky mouthfeel.
- Lemon juice
- Adds acidity that brightens the dressing and balances the richness of the yolks and oil.
- Mustard
- Acts as an emulsifier that helps hold the oil and yolk mixture together and adds sharpness.
- Lettuce
- Provides the crisp, watery base that the dressing coats and the other vegetables rest on.
The step that matters
Cooking the yolk into a smooth paste. Stirring the cooked yolk constantly keeps it from clumping or scrambling, so it blends evenly. Letting it cool before adding the raw yolks prevents the raw yolks from partly cooking on contact with heat, which keeps the dressing smooth.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (lettuce, tomato, cucumber, egg, mustard, sugar, olive):
- Endivefits better
- Chivefits better
- Broccolifits better
- Onionthe original
Fit is the average pairing score against lettuce, tomato, cucumber, egg, mustard, sugar, olive. Candidates are from the same food group and used in at least 100 recipes.
