Scald the milk in a double boiler.
Melt the butter and stir in the flour until smooth.
Stir the butter and flour mixture into the scalded milk and cook for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup and gives it a creamy body.
- Oysters
- Provide the main flavor and tender texture of the soup.
- Flour
- Thickens the milk as it cooks, giving the soup body.
- Butter
- Enriches the soup with fat and helps form the smooth flour base.
The step that matters
Stirring the butter and flour into the scalded milk. Flour clumps if it is added to hot liquid without being fully blended into the butter first. Cooking the mixture for the full 10 minutes lets the starch swell and thicken the milk evenly.
