Oyster Soup
Ingredients
Directions
Prepare the oysters
Boil the milk in a double boiler.
Place a colander over a pan. Drain the oysters in a bowl with 1 cup of water, then strain the oyster liquor through a fine strainer.
Make the soup
Add the oyster liquor to the boiling milk and keep the oysters hot.
Thicken the milk with butter and cornstarch, then add salt and pepper to taste.
Boil for five minutes 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 flavour and the soup's seafood character.
- Milk
- Forms the creamy base of the soup.
- Butter
- Adds richness and fat that rounds out the thickened milk.
- Cornstarch
- Thickens the milk into a smooth, lightly body-filled soup.
The step that matters
Thicken the milk gently. Cornstarch must be heated to boiling to swell and thicken fully, but if it is added to milk that is too hot or boiled too hard, the milk can scorch on the pan base and the starch can clump. Stir it in well and keep the heat controlled so the soup thickens smoothly.
