Ingredients

Directions

Make the veal stock

  1. Add 1 quart of cold water, veal cut into small pieces, onion, and bay leaf to a pot.

  2. Simmer gently for 3 hours.

  3. Strain the mixture and let cool to remove fat.

Make the fish stock

  1. Fillet the plaice and remove the black skin.

  2. Simmer the plaice in 1 quart of cold water for about 1 hour until reduced to shreds.

  3. Rub the cooked plaice through a fine sieve.

  4. Simmer the beards of the oysters in 4 pints of fish stock.

  5. Add oyster liquor.

  6. Strain the oysters and set aside.

Make the soup

  1. Mix the veal stock and fish stock, and bring to a boil.

  2. Melt butter in a stewpan.

  3. Stir in flour and cook for 2-3 minutes.

  4. Pour in hot stock and stir until it boils.

  5. Add milk, oysters, oyster liquor, anchovy essence, and season to taste.

  6. If oysters are large, cut them in halves and add just before serving without cooking.

  7. Stir in cream just before serving.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much aroma chemistry they share, and how many recipes mention both.

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

Butter
Enriches the roux and gives the soup a rich, rounded flavour.
Flour
Thickens the butter and stock into a smooth, velvety base.
Veal knuckle
Adds gelatin and savoury body to the stock.
Oysters
Supply the main briny, sea-like flavour of the soup.
Cream
Adds richness and a silky mouthfeel to the finished soup.
Milk
Lightens the base and adds mild sweetness and body.

The step that matters

Adding the oysters. Oysters toughen and shrink when overcooked, so large ones are halved and added just before serving, with cream stirred in at the end, to keep them tender and the soup smooth.

Flavor stand-ins for the onion

Fit is the average pairing score against veal, butter, flour, milk, cream, oyster, anchovy. 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).
