Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and flavor to the base of the sauce.
- All-purpose flour
- Thickens the milk into a smooth sauce as it cooks.
- Milk
- Forms the liquid body of the sauce, which thickens as it heats.
- Mushrooms
- Provide the main flavor and texture in the sauce.
The step that matters
Stirring the flour and milk. Adding flour gradually while mixing keeps lumps from forming, and stirring constantly as the milk heats prevents scorching and helps the starch thicken evenly into a smooth sauce.
