Why it works: Lettuce and olive match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,580 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Add richness and help thicken the sauce as it is combined.
Cream
Adds richness and a smooth, silky texture to the sauce.
Granulated gelatin
Sets the sauce so it clings to the meat and firms as it cools.
Chicken stock
Adds savoury flavour and liquid to the sauce.
Cooked chicken, veal, or lamb
Provides the base that the sauce coats.

The step that matters

Dip the meat when the sauce is cool, not hot. Gelatin sets as the sauce cools. If the sauce is too hot, it runs off the meat and the coating is thin. Once it is cold, the second dip builds a firmer, even layer that holds on the plate.

Swap the lettuce

How well each one fits the dish's main ingredients (egg, cream, gelatin, chicken, olive):

  1. Capsicumfits better
  2. Potatofits better
  3. Asparagusfits better
  4. Lettucethe original

Fit is the average pairing score against egg, cream, gelatin, chicken, olive. Candidates are from the same food group and used in at least 100 recipes.
