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 ↓
Lettuce Salad
Ingredients
Directions
Prepare the salad
Combine shredded lettuce, chopped onion, peppergrass, celery, and nuts in a bowl.
Make the dressing
Mix vinegar, egg yolks, mustard, salt, sugar, and butter in a separate bowl until well combined.

Return the mixture to the stove and beat until thick, but do not let it boil.
Finish and serve
Fold in the whipped cream just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they set with gentle heat, giving it a smooth, rich body.
- Heavy cream
- Adds richness and a light, airy texture when whipped and folded in.
- Vinegar
- Provides the sharp acidity that balances the sweetness and richness of the dressing.
- Celery
- Adds crisp texture and fresh, slightly vegetal flavor to the salad.
- Butter
- Adds fat for smoothness and a rounder mouthfeel in the cooked dressing.
The step that matters
Cook the dressing without boiling. Egg yolks thicken as their proteins set with gentle heat. If the mixture boils, the yolks can scramble and curdle, leaving the dressing grainy instead of smooth.
Swap the nuts
How well each one fits the dish's main ingredients (lettuce, onion, celery, vinegar, egg, mustard, sugar):
- Sesamefits better
- Lentilsfits better
- Beansfits better
- Nutsthe original
Fit is the average pairing score against lettuce, onion, celery, vinegar, egg, mustard, sugar. Candidates are from the same food group and used in at least 100 recipes.
