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 ↓

Ingredients
Directions
Prepare the vegetables

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the bulk of the salad and provides crisp, fresh texture.
- Celery
- Adds crunch and a fresh, watery bite to the chopped salad.
- Beets
- Adds body, earthy sweetness, and color to the salad.
- Egg yolks
- Emulsify the oil and vinegar, giving the dressing a creamy, cohesive texture.
- Salad oil
- Adds fat and richness, coating the vegetables and carrying flavor.
- Vinegar
- Adds acidity that brightens the dressing and balances the sweetness and fat.
The step that matters
Mixing the dressing. Oil and vinegar separate on their own. The egg yolks and mustard help hold them together as an emulsion, so the dressing coats the vegetables evenly instead of pooling. Add vinegar gradually, only until the mixture is moist, so the dressing does not turn thin and watery.
Swap the celery
How well each one fits the dish's main ingredients (lettuce, cabbage, egg, mustard, sugar, vinegar):
- Tarragonfits better
- Capersfits better
- Dillfits better
- Celerythe original
Fit is the average pairing score against lettuce, cabbage, egg, mustard, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
