Ingredients
Directions
Prepare the herring
Soak the herring overnight.
Clean the herring and remove all bones.
Chop the herring in a bowl.
Make the salad
Add the apples, walnut meats, boiled potatoes, and enough boiled beets to achieve a red color.

Garnish with hard-boiled eggs and olives.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring
- Forms the main body of the salad and supplies its savory, fishy flavor.
- Apples
- Add sweetness, moisture and a crisp texture that contrasts with the fish.
- Walnut meats
- Add crunch and a rich, nutty fat to the chopped mixture.
- Boiled potatoes
- Add starchy bulk that binds the chopped ingredients and softens the texture.
- Boiled beets
- Provide the red color and a mild earthy sweetness.
The step that matters
Chop all ingredients very fine. Fine, even chopping lets the pieces bind together into a cohesive salad rather than separate chunks, and spreads the beet color evenly through the mixture.
Swap the apple
How well each one fits the dish's main ingredients (walnut, meat, potato, sugar, vinegar, egg, olive):
- Figfits better
- Avocadofits better
- Cherryfits better
- Applethe original
Fit is the average pairing score against walnut, meat, potato, sugar, vinegar, egg, olive. Candidates are from the same food group and used in at least 100 recipes.
