Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole white fish
- Main protein, cooked gently in salted water so it stays moist and tender.
- Butter
- Melted to start the sauce and adds richness and flavour to the fish.
- All-purpose flour
- Cooked with the melted butter, it thickens the sauce into a smooth gravy.
- Hard boiled eggs
- Sliced into the sauce and used as a garnish, adding richness and texture.
The step that matters
Adding the boiling water to the butter and flour. Adding the liquid gradually while stirring continuously lets the flour disperse evenly, which prevents lumps and gives a smooth sauce. Dumping it in at once makes lumps that are hard to remove.
