Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that coats the flour and forms a smooth base, carrying flavor into the sauce.
- Flour
- Starch that thickens the milk as it heats, giving the sauce its body.
- Milk
- Liquid that forms the body of the sauce and gives it a creamy richness.
The step that matters
Adding the milk gradually while stirring. Flour starch disperses evenly only when liquid is added slowly and stirred. Adding it all at once can trap dry clumps of flour that stay lumpy even after heating.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
