Egg and lemon barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked fish
- Forms the main body of the salad, giving it substance and flaky texture.
- Hard boiled egg yolks
- Mashed into the paste, they add richness and a creamy body to the dressing.
- Sardines
- Mashed into the paste, they add a savoury, strong flavour and richness.
- Boiled or mayonnaise dressing
- Adds moisture and fat, binding the paste and coating the fish.
The step that matters
Mashing the yolks and sardines to a smooth paste. If the paste stays lumpy, the dressing will not coat the fish evenly and pockets of strong sardine flavour can taste uneven. Mashing the yolks thoroughly first helps them blend smoothly into the dressing.
Swap the lettuce
How well each one fits the dish's main ingredients (fish, egg, lemon):
- Asparagusfits better
- Spinachfits better
- Shallotfits better
- Lettucethe original
Fit is the average pairing score against fish, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
