Medium White Sauce

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

  1. Melt the butter in a saucepan over medium heat.

  2. Stir in the flour and cook for 1-2 minutes until bubbly.

  3. Gradually whisk in the scalded milk until smooth.

  4. Add salt and pepper, and cook until thickened.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Melts to form the fat base that the flour is cooked into.
Flour
Thickens the milk as its starch swells when heated, forming the sauce body.
Milk
Forms the liquid base that the thickened roux turns into a smooth sauce.

The step that matters

Cooking the flour into the butter before adding milk. Cooking the flour for 1-2 minutes until bubbly cooks off its raw taste and helps it blend smoothly. Adding milk too soon or without whisking can leave lumps.
