Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main savoury flavour and body of the dish.
- Butter
- Adds fat and richness, and helps form the base of the sauce.
- Flour
- Thickens the melted butter and milk into a smooth sauce.
- Milk
- Forms the liquid base of the sauce, giving it creaminess once thickened.
- Grated cheese
- Melts into the sauce to add richness, flavour and body.
- Egg
- Adds structure and body to the mixture as it sets gently with heat.
The step that matters
Gradually pour in milk. Adding milk slowly to the butter and flour lets the starch mix in evenly, preventing lumps and giving a smooth sauce.
