Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour, giving it a smooth, rich body.
- Flour
- Thickens the butter and liquid together so the sauce turns smooth and coats the fish.
- Cream or milk
- Forms the liquid base, adding richness and a silky, creamy texture.
- Anchovy
- Melts into the sauce, adding savoury depth that rounds out the flavour.
- Indian soy
- Adds salty, savoury depth and a darker colour to the sauce.
- Lemon juice
- Adds acidity that brightens the rich cream and balances the savoury flavours.
The step that matters
Stirring over low heat until just before boiling. Cream and milk can scorch or curdle if overheated, and flour-thickened sauces can turn lumpy or grainy if they boil hard or unevenly. Gentle, steady heat keeps the sauce smooth and silky.
