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 ↓
Herring Salad
Ingredients
Directions
In a large bowl, combine the flaked herring, diced apples, diced potatoes, chopped nuts, chopped pickle, chopped onion, chopped green pepper, capers, and the yolks of the hard boiled eggs.
Mix the yolks with a little vinegar, then add to the salad mixture. Stir everything together, adding more vinegar to taste if needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Provides the main fish flavour and the flaked body of the salad.
- Apples
- Adds crisp texture and a touch of sweetness against the salty fish.
- Potatoes
- Adds bulk and a soft, starchy texture that holds the salad together.
- Hard boiled eggs
- Yolks are mashed with vinegar to add richness and bind the salad.
- Pickle
- Adds sharp acidity and a briny crunch that cuts through the fish.
The step that matters
Mixing the egg yolks with vinegar. Mashing the yolks with vinegar first lets them blend into a smooth dressing instead of leaving dry lumps. Adding vinegar gradually and tasting lets the cook balance acidity without making the salad sour.
Swap the apple
