Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main body and briny, savory flavor of the soup.
- Sweet milk
- Adds creaminess and a mild sweetness that softens the briny flavor.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the soup.
- Flour
- Thickens the soup slightly as its starch swells in the hot liquid.
The step that matters
Rub the butter into the flour and stir it into the soup.. Coating the flour with butter helps its starch disperse evenly instead of clumping into lumps when it hits the hot liquid. Stir steadily as it goes in.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
