Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and body of the soup.
- Milk
- Forms the liquid base and adds creaminess and sweetness.
- Butter
- Adds richness and fat to the finished soup.
- Flour
- Thickens the soup slightly as it cooks.
- Whipped cream
- Adds lightness and a smooth, rich finish.
The step that matters
Stirring while bringing the milk and oysters to a boil. Milk can scorch or form a skin on the bottom of the pan when heated, and constant stirring spreads heat evenly. Keeping the mixture moving helps prevent sticking and curdling, so the soup stays smooth.
