Why it works: Lettuce and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 372 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
Italian Egg Salad
Ingredients
Directions
Prepare
Shell the eggs and cut them into thick rings.
Wash and lightly dry the lettuce, then tear it into pieces.
Trim the crusts from the toast and place it in a salad bowl.
Boil the macaroni in salted water until tender, then cut it into short lengths.
Make the dressing
Whisk the cream until thick, then stir in the mayonnaise and parsley.
Assemble
Layer the lettuce on the toast, followed by eggs, macaroni, and dressing; repeat until all ingredients are used.

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 protein of the salad, set firm for clean slices.
- Lettuce
- Adds crisp texture and fresh moisture that contrasts with the rich dressing.
- Toast
- Forms a sturdy base that soaks up some dressing without collapsing completely.
- Mayonnaise dressing
- Adds fat and creaminess that binds the layers and carries flavour.
- Cream
- Whipped to thickness, it lightens the dressing and adds a silky richness.
- Macaroni
- Adds soft, chewy starch that gives the salad bulk and texture.
The step that matters
Whisk the cream until thick. Cream must be whipped to a stable, thick state before mayonnaise is folded in; under-whipped cream stays runny and thins the dressing, while over-whipping can turn it grainy and separate it.

Fit is the average pairing score against egg, lettuce, cream, capers. 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).
