Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whitefish
- Provides the main body of the dish, cooking gently in simmering water to become flaky.
- Butter
- Adds richness and a silky mouthfeel to the gravy and the dressed fish.
- Flour
- Thickens the boiling water into a smooth gravy when cooked briefly in the melted butter.
- Hard-boiled eggs
- Add body and a mild, rich flavour to the sauce and garnish.
The step that matters
Gradually add the boiling water to the flour and butter. Adding the liquid slowly while stirring keeps the flour dispersed, so the gravy thickens smoothly instead of forming lumps.
