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
- Chicken
- Forms the bulk of the salad and provides its main protein texture.
- Mayonnaise
- Binds the chopped ingredients and adds richness and moisture.
- Egg yolk
- Emulsifies and thickens the dressing as it cooks.
- Flour
- Thickens the dressing so it sets to a stable, spoonable consistency.
- Heavy cream
- Adds fat and smoothness, mellowing the dressing's tang.
- Vinegar
- Adds acidity that balances the richness of the dressing.
The step that matters
Cook the dressing over low heat, stirring until thick. Egg yolk can scramble if it gets too hot or is left unstirred. Gentle heat and constant stirring let the yolk and flour thicken the dressing smoothly without curdling.
Swap the lettuce
How well each one fits the dish's main ingredients (chicken, olive, mushroom, egg, butter, sugar, mustard):
- Capsicumfits better
- Asparagusfits better
- Shallotfits better
- Lettucethe original
Fit is the average pairing score against chicken, olive, mushroom, egg, butter, sugar, mustard. Candidates are from the same food group and used in at least 100 recipes.
