Why it works: Lettuce and watercress match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 307 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Olive Salad
Ingredients
Directions
Make the sauce
Beat the egg until frothy, then mix in the sour cream.
Heat the mixture in a small saucepan over low heat until it thickens.
Combine vinegar, onion, bay leaf, clove, celery, and peppercorns in another saucepan and boil for a few minutes.
Strain the boiled mixture into the egg sauce, stirring until completely cool.
Assemble and serve
Prepare a salad with lettuce, watercress, beetroot, chervil, chicory, and mustard and cress.
Pour the sauce over the salad and arrange stoned olives filled with flaked and seasoned anchovies around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg thickens the sour cream base into a smooth, lightly set sauce when heated gently.
- Sour cream
- Adds richness and a creamy body to the dressing.
- Vinegar
- Adds acidity that sharpens the sauce and balances the richness of the cream.
- Anchovies
- Contribute a salty, savoury depth to the olives and the dish.
The step that matters
Heating the egg and sour cream mixture over low heat. Egg proteins set when heated, so over high heat or for too long the sauce can curdle or turn grainy. Gentle, low heat lets it thicken smoothly.
Swap the clove
How well each one fits the dish's main ingredients (egg, cream, onion, celery, vinegar, lettuce, watercress):
- Tarragonfits better
- Capersfits better
- Parsleyfits better
- Clovethe original
Fit is the average pairing score against egg, cream, onion, celery, vinegar, lettuce, watercress. Candidates are from the same food group and used in at least 100 recipes.
