Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body and earthy flavour, softening as they cook.
- Butter
- Adds richness and fat, and helps begin the roux.
- Flour
- Thickens the sauce when cooked with butter to form a roux.
- Milk
- Forms the liquid base of the sauce, which thickens as it is whisked in.
The step that matters
Gradually whisking in the milk. Adding milk too quickly to the roux can trap lumps of flour that do not smooth out. Adding it slowly while whisking lets the starch disperse evenly, giving a smooth sauce as it thickens.
