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, once scalded, carries the flavor of the dish.
- Oysters
- Provide the main flavor and tender texture, cooking briefly in their own liquor.
- Butter
- Adds richness and carries the flour so it blends smoothly into the milk.
- Flour
- Thickens the milk into a smooth, creamy soup when cooked with the butter.
The step that matters
Stir the butter and flour mixture into the scalded milk until smooth. Flour thickens only when its starch is hydrated and heated, and adding the roux to hot milk while stirring prevents lumps. Stirring keeps the starch dispersed so the soup thickens evenly.
