What each ingredient does
- Anchovies
- Dissolve into the liquid to give the sauce a savory, salty depth.
- Flour
- Thickens the sauce as its starch swells when heated in liquid.
- Butter
- Adds richness and a smooth, velvety mouthfeel to the finished sauce.
The step that matters
Heating the flour mixture. Stir the cooled liquid, flour and butter over low heat so the flour dissolves evenly and thickens without lumps. Flour starch can stick and scorch on the base of the pan if left unstirred, and stopping at the first boil keeps the sauce smooth.
