Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Salt-cured fish is the main ingredient, providing savoury flavour and a firm, flaky texture when cooked.
- Vinegar
- Adds acidity that sharpens the flavour and balances the saltiness of the fish.
- Shredded horseradish
- Contributes a pungent, sharp aroma and heat that cuts through the richness of the fish.
The step that matters
Boil the fish slowly. Vigorous boiling toughens fish proteins and can break the flesh apart. A gentle simmer cooks the fish evenly while keeping it tender and intact.
