Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, and forms the base of the roux.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Anchovy paste
- Adds salty, savoury depth that gives the sauce its fishy character.
The step that matters
Adding the water. Flour starch clumps when liquid meets it all at once. Adding the water gradually while stirring constantly lets each starch granule separate and hydrate evenly, so the sauce becomes smooth instead of lumpy.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
