Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Provide the main fish flavour and the body of the salad.
- Goose fat
- Adds richness and a silky moisture that coats the other ingredients.
- Hard boiled eggs
- Add body and a creamy richness to the mixture.
- Sour apples
- Add acidity that balances the fatty fish, meat and fat.
- Cream
- Adds softness and moisture to the dressing.
- Mustard
- Adds sharpness that cuts through the richness of the fat.
The step that matters
Gently mix everything together without breaking the pieces. Cut pieces of fish, potato and egg hold their shape only if handled gently. Vigorous stirring breaks them down, turning the salad mushy and giving it an uneven texture.
