What each ingredient does
- Flour
- Thickens the water and butter mixture into a smooth, sauce-like consistency as it heats.
- Butter
- Adds richness and flavour, and gives the finished sauce a glossy, smooth finish.
The step that matters
Stirring the flour and butter before adding the water. Stirring the flour into the melted butter until smooth coats the starch grains in fat, which helps prevent lumps when the cold water is added.
