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 ↓
Chicken Salad
Ingredients
Directions
Prepare
Remove skin and gristle from the boiled chicken and chop it finely.
Cut the lettuce into quarters and soak it in water with ice to crisp.
Make the dressing
In a bowl, mix the egg yolks, mustard, cayenne pepper, and salt with a fork.
Gradually stir in the sweet oil and a little vinegar until well combined.
Mix half of the dressing with the chopped chicken.
Assemble
Place the chicken mixture in the center of a flat dish.
Dry the lettuce and arrange it neatly around the chicken.
Drizzle the remaining dressing over the lettuce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and vinegar into a thick, creamy dressing that holds the salad together.
- Sweet oil
- Provides fat and richness, and with the egg yolks forms the body of the dressing.
- Mixed mustard
- Helps stabilise the emulsion and adds a sharp, savoury bite.
- Lettuce
- Adds crisp texture and fresh contrast to the rich chicken and dressing.
The step that matters
Gradually stir in the sweet oil. Adding the oil slowly while stirring lets the egg yolk emulsify it into a smooth dressing. Pouring it in too fast can cause the mixture to split and look greasy.
Swap the lettuce
How well each one fits the dish's main ingredients (chicken, egg, mustard, pepper, vinegar):
- Capsicumfits better
- Horseradishfits about as well
- Lettucethe original
- Shallotfits about as well
Fit is the average pairing score against chicken, egg, mustard, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
