Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that thickens into the sauce.
- Butter
- Carries flavor and adds richness to the sauce.
- All-purpose flour
- Thickens the sauce when cooked with butter and milk.
The step that matters
Reduce heat to low and cook, whisking occasionally, until thickened. Flour thickens only as its starch swells in hot liquid. Cooking gently while whisking keeps the sauce smooth and prevents lumps or scorching on the bottom of the pan.
