Name: Egg Salad
Ingredients: 3 hard-boiled eggs; 1 small crisp lettuce; a few slices of beetroot; 2 teaspoons of capers; 1 teaspoon of chopped parsley; 1 slice of toasted bread; 1 tablespoon of cream (optional); 2 teaspoons of mayonnaise sauce

Why it works: Lettuce and beetroot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 678 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Directions

Prepare

Cut the eggs into thick slices.
Wash, trim, and dry the lettuce thoroughly.

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

What each ingredient does

Hard-boiled eggs: Provide the main body and rich flavour of the salad as thick slices.
Mayonnaise: Adds fat and moisture, binding the layers and giving a creamy texture.
Lettuce: Adds crisp texture and freshness between the layers.
Capers: Add a sharp, briny acidity that cuts through the rich eggs and mayonnaise.
Cream: Whipped and mixed with mayonnaise, it adds lightness and extra richness.

Fit is the average pairing score against egg, lettuce, beetroot, capers, bread, cream, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
