Ingredients
Directions
Melt the butter in a saucepan over medium heat.

Gradually add the water, stirring constantly until the sauce thickens.
Serve immediately or keep warm by placing the saucepan in a bowl of hot water.

What each ingredient does
- Butter
- Adds fat and flavour, and enriches the sauce.
- All-purpose flour
- Thickens the sauce when cooked with fat and liquid.
- Water
- Forms the liquid base that the flour thickens into a sauce.
The step that matters
Adding the water to the flour mixture. Adding liquid gradually while stirring constantly keeps the flour dispersed, which prevents lumps and lets the sauce thicken smoothly as the starch swells with heat.
