Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid into a smooth sauce as it heats and boils.
- Butter
- Adds richness and a silky, glossy texture as it melts into the sauce.
The step that matters
Pour the flour mixture into boiling water while stirring briskly. Adding the flour paste to hot liquid while stirring keeps the starch dispersed, so the sauce thickens smoothly instead of forming lumps.
