Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted to form a fat base that carries the flour and adds richness.
- Flour
- Thickens the milk into a smooth sauce as its starch swells when heated.
- Milk
- Forms the liquid body of the sauce, which thickens as it heats.
The step that matters
Adding the milk gradually while stirring. Pouring the milk in slowly while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly without lumps.
