Boiled White Fish
Ingredients
Directions
Poach the fish
Lay the fish open in a dripping pan with the back down.
Nearly cover the fish with water and add the salt.
Cover tightly and simmer for 30 minutes.
Make the sauce and serve
Dress the fish with gravy, butter, and pepper, and garnish with sliced eggs.
For the sauce, melt a piece of butter the size of an egg in a saucepan.
Add 1 tablespoon of flour and ½ pint of boiling water, stirring until thick.
Add the sliced hard‑boiled eggs to the sauce and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Provides the main body of the dish, cooked gently in simmering water until tender.
- Butter
- Adds richness and a silky mouthfeel to the sauce and finished fish.
- Flour (in the method)
- Thickens the boiling water into a smooth, stable gravy-style sauce.
- Hard boiled eggs
- Add a firm, mild texture and creamy yolk flavour to the garnish and sauce.
The step that matters
Simmer covered with the fish nearly submerged. Gentle, covered simmering cooks the fish through without toughening or breaking it. Boiling hard can make the flesh dry and flake apart, so keep the liquid at a quiet simmer.
