What each ingredient does
- Cod's head and shoulders
- Forms the main body of the dish and provides the flesh that becomes tender as it cooks.
- Butter
- Adds richness and a silky moistness when melted over the cooked fish.
- Lemon
- Adds acidity that brightens the flavour of the rich fish and butter.
The step that matters
Simmer until cooked through. Fish protein sets as it heats and turns dry and tough if overcooked, so the simmer should be gentle and stopped once the flesh is opaque and flakes easily.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
