Oyster Croquettes

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the oysters

  1. Place the oysters in a saucepan over medium heat and cook slowly until they open.

  2. Drain the oysters well through a colander.

  3. Chop the opened oysters and set aside.

Make the filling

  1. In a separate pan, melt the butter and sauté the chopped onion until soft.

  2. Stir in the flour and cook for 1 minute.

  3. Gradually add the cream, stirring until thickened.

  4. Add the chopped oysters and parsley, mixing well.

  5. Allow the mixture to cool, then shape into croquettes.

Fry and serve

  1. Fry the croquettes in hot oil until golden brown.

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 bulk of the croquette filling.
Butter
Adds richness and fat, and helps cook the onion without browning it.
Flour
Thickens the butter and cream into a sauce that holds the filling together.
Rich cream
Adds moisture and body, thickening into a smooth binding sauce.
Chopped onion
Adds aromatic sweetness and savoury depth to the filling.

The step that matters

Cooling the filling before shaping. A warm, loose filling will not hold its shape and can burst or spread in the hot oil. Chilling lets the flour-thickened cream set firmly enough to form and fry cleanly.

Swap the parsley

How well each one fits the dish's main ingredients (oyster, onion, butter, flour, cream):

  1. Capersfits better
  2. Garlicfits better
  3. Nutmegfits about as well
  4. Parsleythe original

Fit is the average pairing score against oyster, onion, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
