Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and carries flavour through the sauce.
- Flour
- Starch thickens the milk into a smooth, coating sauce as it heats.
- Milk
- Forms the liquid base that the flour thickens into a creamy sauce.
- Anchovy essence
- Provides the savoury, salty fish flavour that defines the sauce.
The step that matters
Gradually add the milk while stirring well. Flour starch must be dispersed evenly in the fat before and as the liquid is added. Adding milk too fast or stopping to stir lets starch clump into lumps that won't smooth out, leaving the sauce grainy.
