Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when stirred into the hot mixture, binding it and giving it a soft, tender body.
- Flour
- Thickens the milk into a smooth, cohesive sauce that holds the fish together.
- Butter
- Adds richness and a silky mouthfeel, carrying flavour through the dish.
- Milk
- Forms the liquid base that thickens and gives the dish its creamy texture.
The step that matters
Thicken with flour mixed in cold milk. Flour must be blended into cold milk first so its starch disperses evenly; added to hot liquid directly it clumps. Starch swells and thickens as the mixture heats, so the sauce turns smooth rather than lumpy.
