Why it works: Beetroot and potato match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 330 recipes mention both. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
An Excellent Herring Salad
Ingredients
Directions
Prepare the herring
Soak the herring.
Skin the herring.
Split the herring.
Lay the two sides of the herring on a dish.
Slice the herring slopingly.
Assemble the salad
Arrange slices of beetroot, cold boiled potatoes, and pickled gherkins over the fish.
Add chopped apples, minced yolks and whites of hard-boiled eggs, and any other decorative ingredients.
Place these ingredients in small heaps of contrasting colors on the salad.

Make the dressing
Rub the yolk of one hard-boiled egg smooth with salt.
Add oil and vinegar to the egg yolk.
Dilute the egg yolk mixture with thick sour cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Norway herring
- Forms the main body of the salad and supplies its characteristic savoury, fishy flavour.
- Beetroot
- Adds sweet, earthy flavour and a deep red colour that contrasts with the pale fish.
- Cold boiled potatoes
- Provide bulk and a soft, starchy texture that balances the rich fish and dressing.
- Sharp apples
- Add tartness and a crisp texture that cuts through the richness of the herring and cream.
- Hard-boiled egg yolks
- Mashed into a smooth base that gives the dressing body and a creamy, rich texture.
- Thick sour cream
- Adds creaminess and moisture to the dressing, with a mild tang that softens the vinegar.
The step that matters
Dilute the egg yolk mixture with thick sour cream.. The yolk, oil and vinegar form a fragile emulsion. Adding the cream steadily and stirring well keeps the dressing smooth and stops it splitting or turning grainy.
Flavor stand-ins for the apple

Fit is the average pairing score against beetroot, potato, egg, vinegar, cream, celery, beef. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
