What each ingredient does
- Stock fish
- Is the main protein, softened by soaking and then gently simmered until tender.
- Clarified butter
- Adds richness and fat, carrying flavour as a serving accompaniment.
- Hot potatoes
- Adds starch and bulk, soaking up the flavour of the fish and butter.
The step that matters
Bring to a boil, skim the surface, then simmer. Skimming removes foam and impurities that would cloud the liquid and taint flavour. Simmering gently rather than boiling hard keeps the fish tender and intact instead of tough and falling apart.
