My Mother's Oyster Soup

Ingredients

Directions

Prepare the base

  1. Heat 1 quart of sweet milk in a double boiler.

  2. Rub 1 tablespoon butter with 1 tablespoon cornstarch or flour in a bowl.

  3. Stir the butter mixture into the hot milk.

  4. Add 1 thin slice breakfast bacon and 1 stalk celery, and boil.

Add the oysters

  1. Pour a few drops lemon juice or vinegar over 1 pint oysters and bring them to a boil in their liquor.

  2. Drain the oysters; if they curdle, wash them in cold water.

  3. Add the oysters and their skimmed liquor to the milk mixture.

  4. Season with salt and pepper, and serve immediately.

Serve

  1. Break up snowflake crackers in a soup tureen and pour the oyster soup over them before serving.

    Shared aroma: isobutyraldehyde (malty, green).

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sweet milk
Forms the liquid base of the soup, giving it its body and creamy richness.
Butter
Adds richness and fat, and is cooked with the starch to form a smooth thickener.
Cornstarch or flour
Thickens the milk as it heats, giving the soup a smooth, velvety body.
Oysters
Provide the main flavor and tender texture, and their liquor adds savory depth.
Breakfast bacon
Adds smoky, savory flavor to the milk as it simmers.

The step that matters

Adding the oysters to the milk. Oysters curdle and toughen when boiled too long or too hot, so they should only be brought to a gentle boil until their edges curl. Draining and rinsing them if they curdle helps keep the soup smooth.

Flavor stand-ins for the celery

How well each one fits the dish's main ingredients (milk, butter, flour, oyster, lemon, pepper):

  4. Celerythe original

Fit is the average pairing score against milk, butter, flour, oyster, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
