Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole whitefish
- Forms the main body of the dish; gentle poaching keeps its flesh moist and flaky.
- Butter
- Adds richness and a smooth, savoury flavour to the dressing and gravy.
- Flour
- Thickens the gravy as its starch swells in the hot liquid.
- Hard-boiled eggs
- Add body and a soft, rich texture to the gravy and garnish.
The step that matters
Simmer, do not boil, the fish. Vigorous boiling toughens and breaks up delicate fish flesh. Gentle simmering heat cooks the fish through while keeping it moist and intact.
“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.
