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
Soak the herrings overnight, then cut them into small pieces.
Cook and peel the potatoes, then let them cool before chopping.
Chop the cooked red beets, onions, sour apples, and hard-boiled eggs.
Assemble and dress
In a large bowl, combine the chopped ingredients with the roasted veal.
In a separate bowl, mix the sweet oil, vinegar, stock, pepper, and mustard to taste.
Pour the sauce over the salad mixture and stir to combine.
Rest
For best flavor, let the salad sit overnight in an earthen dish.

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 flavor and the salad's tender, flaked texture.
- Potatoes
- Add body and bulk, soaking up dressing so the salad holds together.
- Sweet oil
- Carries flavor and gives the dressing richness and a smooth mouthfeel.
- Vinegar
- Adds acidity that sharpens the flavors and balances the fat and fish.
- Sour apples
- Contribute tart acidity and a crisp contrast to the soft ingredients.
- Hard-boiled eggs
- Add creamy richness and a firm, soft texture to the mixture.
The step that matters
Resting overnight. Time lets the vinegar, oil, and seasonings penetrate the chopped ingredients and blend the flavors, so the salad tastes more cohesive than when freshly mixed.
Swap the apple
How well each one fits the dish's main ingredients (potato, onion, veal, egg, vinegar, pepper, mustard):
- Lemonfits better
- Limefits better
- Avocadofits better
