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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg
- Mashed into the dressing, it adds body and richness that help it cling to the leaves.
- French mustard
- Its emulsifying compounds help the oil and vinegar blend into a smooth, stable dressing.
- Oil
- Coats the leaves and carries flavour, giving the dressing its richness and mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
The step that matters
Mix the dressing well. Oil and vinegar separate unless thoroughly whisked or blended with an emulsifier like mustard and egg. Poorly mixed dressing pools at the bottom of the bowl and leaves the greens unevenly coated.
Swap the tomato
How well each one fits the dish's main ingredients (lettuce, chicory, celery, egg, mustard, chive, tarragon):
- Beetrootfits better
- Shallotfits better
