What each ingredient does
- Butter
- Adds richness and flavour, and its fat gives the sauce a smooth, rounded mouthfeel.
- Flour
- Thickens the liquid as its starch swells when heated, giving the sauce body.
The step that matters
Removing the saucepan from the heat before adding the remaining butter. If the sauce is still very hot, the added butter can melt too fast and separate into greasy droplets. Off the heat, the butter melts gently and emulsifies into the thickened liquid, keeping the sauce smooth.
