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 flavour and the salad's bulk of chopped texture.
- Potatoes
- Add starchy body that soaks up the dressing and gives the salad substance.
- Sour cream
- Adds richness and a tangy creaminess to the sauce.
- Sweet oil
- Carries fat-soluble flavour and keeps the chopped pieces moist and glossy.
- Vinegar
- Adds acidity that brightens the flavours and balances the fish and fat.
The step that matters
Letting the salad stand overnight. Resting lets the chopped ingredients absorb the oil, vinegar and seasonings, so flavours blend and the dressing thickens into the pieces. Serving too soon leaves the salad tasting separate and sharp.
Swap the apple
How well each one fits the dish's main ingredients (potato, onion, veal, egg, vinegar, pepper, mustard):
- Lemonfits better
- Limefits better
