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 ↓
Espagnole Sauce
Ingredients
Directions
Prepare the sauce
Make a white sauce.
Beat the egg yolks slightly and dilute with cream.
Dissolve gelatin in hot chicken stock.
Mix the stock with the white sauce.
Coat the meat
When cool, dip pieces of cooked meat in the sauce.
When cold, dip again for a second coating.
Serve
Serve very cold on lettuce leaves and garnish with stuffed olives.

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):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- 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.
