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 flesh that forms the body of the salad.
- Potatoes
- Add starchy bulk that holds its shape once boiled and cut into squares.
- Brussels sprouts
- Contribute tender body and a mildly bitter, earthy flavour.
- Vinegar
- Adds acidity that brightens the fish and cuts its richness.
- Oil
- Adds fat that carries seasoning and gives the salad a smooth mouthfeel.
The step that matters
Boil the vegetables until tender. Undercooked potatoes stay hard and chalky, while overcooked ones crumble when cut into squares. Boiling until just tender gives pieces that hold their shape and absorb the dressing evenly.
