Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves into the water to form a sweet syrup that forms the base of the sauce.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
- Flour
- Thickens the liquid and gives the sauce body.
The step that matters
Mix the butter with the flour until smooth before adding. Flour clumps when it meets hot liquid unless it is first blended into fat. Working it smooth beforehand lets it disperse evenly and thicken the sauce without lumps.
