Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Its starch thickens the sauce as it heats in the liquid.
- Boiling water
- Hydrates the flour so its starch can swell and thicken the sauce.
- Butter
- Adds richness and a glossy, smooth finish to the sauce.
- Wine
- Adds acidity and aroma that brighten the flavour of the sauce.
The step that matters
Gradually add the boiling water while stirring. Adding hot liquid slowly while stirring lets the flour disperse evenly, which prevents lumps from forming as the starch thickens.
