Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the salad and soak up the hot dressing.
- Salt herrings
- Provide the main savoury, salty flavour and the fish element of the salad.
- Vinegar
- Adds acidity that sharpens the flavour and balances the fat and salt.
- Lard
- Adds fat that gives the dressing richness and a smoother mouthfeel.
The step that matters
Pour the hot mixture over the salad. The dressing must be boiling hot so the warm potatoes absorb it while still porous. Pouring it over cold potatoes leaves the salad flat and under-seasoned.
Swap the onion
How well each one fits the dish's main ingredients (potato, egg, pepper, vinegar):
- Capsicumfits better
