Why it works: Potato and lettuce match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 322 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Egg and Fish Salad
Ingredients
Directions
Make the fish mixture
Slice the eggs and mix with equal parts of salmon.
Rub the mixture into a paste and add coarse sea salt, paprika, butter, and vinegar; mix until smooth.
Assemble and serve
Form nests with the mashed potatoes and fill each with a ball of the fish mixture.
Place lettuce leaves on a dish and arrange the potato nests on top.
Add a spoonful of mayonnaise on each fish ball.
Use the egg whites to create a border on the leaves and place pieces of jelly in each egg ring.
Serve very cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Give the fish mixture body and a soft, creamy texture.
- Salmon
- Provides the main fish flavour and bulk of the filling.
- Butter
- Adds fat for richness and a smoother, silkier mixture.
- Vinegar
- Adds acidity that brightens the rich fish and egg flavours.
- Mashed potatoes
- Form the starchy nests that hold the fish mixture in shape.
- Mayonnaise
- Adds fat and moisture to the fish balls for a smooth finish.
The step that matters
Rub the mixture into a paste. The fish and egg must be worked until smooth so the filling holds together and has an even texture. Under-mixing leaves lumps, while the fat from butter needs to be fully incorporated to avoid a greasy, separated filling.
