Ingredients
Directions
Make the sauce
In a saucepan, melt the butter or beef fat over medium heat until it boils.
Add the flour and stir as it cooks for a minute.
Gradually add the water, stirring continuously.
Season with salt and pepper.
Finish and vary
For added flavor, use 1 tablespoon of beef fat and add ½ tablespoon of butter just before serving.
For milk sauce, substitute water with milk.
For brown sauce, brown the fat and flour before adding water as above.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter or beef fat
- Carries the flavor and fat that the flour cooks into, giving the sauce richness.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Water
- Forms the liquid base that the flour thickens into a sauce.
The step that matters
Adding the water. Pouring liquid in all at once or without stirring lets the flour clump into lumps. Adding it gradually while stirring keeps the starch evenly dispersed so the sauce thickens smoothly.
“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.
