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 carries flavour, giving the sauce richness.
- Flour
- Starch that thickens the milk into a smooth, creamy sauce as it cooks.
- Milk
- Liquid base that hydrates the starch and forms the body of the sauce.
The step that matters
Adding the milk gradually. Pouring the milk in slowly while stirring lets the flour and butter mixture disperse evenly. Adding it all at once can trap dry clumps of starch that stay lumpy.
“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.
