Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the body of the mould and gives it its main flavour.
- Egg
- Binds the mixture so it holds its shape when turned out.
- Butter
- Adds richness and carries flavour through the sauce base.
- Flour
- Thickens the milk into a smooth sauce that holds the fish together.
- Milk
- Forms the liquid base of the sauce, adding moisture and softness.
- Anchovy essence
- Adds a salty, savoury depth of flavour to the fish mixture.
The step that matters
Bring the sauce to a boil and cool it slightly before adding the egg. Flour must be cooked through in the boiling milk to thicken properly and lose its raw taste. Adding a beaten egg to a very hot mixture can scramble it, leaving uneven texture in the mould.
