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
Prepare the herring
Soak the salted herrings in cold water to reduce saltiness.
Remove the bones from the herring.
Mince the herring.
Make the salad
Chop the cold meat, beetroot, potato, apple, and cucumber, keeping the total quantity equal to the herring.
Combine the minced herring and chopped ingredients in a bowl.
In a cup, mix cream, sugar, vinegar, and pepper.
Add the mixture to the bowl.
Blend until it reaches a paste-like consistency.
Spread the mixture on a flat dish.
Garnish and serve
Garnish with minced beetroot.
Mince the egg whites and yolks separately for decoration.
Arrange the egg garnishes in the center and around the border.
Add a fringe of small pickled onions.
Serve with a sauce of cream, vinegar, mustard, and sugar, or with oil, vinegar, and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salted herrings
- Provide the main fish flavour and the bulk of the salad's body.
- Cream
- Adds richness and a smooth, moist texture that binds the chopped ingredients.
- Vinegar
- Adds acidity that sharpens the flavour and balances the fish and cream.
- Boiled potatoes
- Add starch and softness, helping the mixture hold a spreadable paste-like texture.
- Beetroot
- Adds colour and an earthy sweetness to the salad and its garnish.
The step that matters
Soak the salted herrings. Salt is drawn out by soaking in cold water. Too short a soak leaves the salad overly salty, while too long can leave the fish bland, so tasting during soaking matters.
Swap the apple
How well each one fits the dish's main ingredients (meat, egg, potato, cucumber, onion, sugar, pepper):
- Avocadofits better
- Limefits better
- Lemonfits better
- Applethe original
Fit is the average pairing score against meat, egg, potato, cucumber, onion, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
