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 Sallad
Ingredients
Directions
Prepare the lettuce
Soak the lettuce in water with ice.
Make the dressing
In a flat dish, mix egg yolks, mustard, cayenne pepper, and salt with a fork.
Gradually stir in sweet oil while mixing continuously, then add a little vinegar.
Assemble and serve
Combine half of the dressing with the chopped meat and mix well.
Place the mixture in the center of a flat dish and dry the lettuce with a napkin.
Arrange the lettuce around the meat and 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
- Act as an emulsifier, holding the oil and vinegar together in a smooth, thick dressing.
- Sweet oil
- Provides fat and richness, giving the dressing its body and silky mouthfeel.
- Mixed mustard
- Adds sharpness and helps stabilise the emulsion of the dressing.
- Vinegar
- Adds acidity that brightens the dressing and balances the rich oil and yolks.
- Boiled chicken
- Provides the main protein and substance of the salad, coated by the dressing.
The step that matters
Adding the oil to the yolks. Oil must be added slowly while whisking continuously, so that tiny droplets form and disperse in the yolk. Adding it too fast breaks the emulsion, leaving a greasy, separated dressing.
Swap the lettuce
