Prepare
Wash the oysters in cold water and drain.
Make the soup
Set the oyster liquor in a soup kettle over heat and bring to a boil, skimming off any scum.

Add the butter and season with salt and pepper.
Let it boil once and serve immediately.

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 tender bite of the soup.
- Butter
- Adds richness and a smooth, silky mouthfeel to the broth.
- Cornstarch
- Thickens the liquid into a light, smooth body when heated.
- Rich new milk
- Forms the creamy base that carries the oyster flavor.
The step that matters
Thickening with cornstarch. Cornstarch must be mixed with a little cold milk before it goes in, so it disperses without lumps. It thickens when heated, so the soup should be kept at a gentle simmer and not boiled too long after adding it, or the starch may thin and the milk may separate.
