Oyster Croquettes

Ingredients

Directions

Prepare the oysters

  1. Drain the oysters in a colander and chop them very fine.

  2. Strain the oyster juice and boil it down by half.

Make the custard base

  1. Mix the butter smoothly with the flour and stir into the reduced juice until it forms a thick sauce.

  2. Add the minced parsley, thyme, sweet marjoram, chopped oysters, cream, beaten eggs, and salt. Stir until it forms a thick paste.

  3. Spread the mixture on a large dish and let it cool until stiff.

Shape, coat and fry

  1. Dust your hands with flour and shape the mixture into small pear-shaped cones.

  2. Dip each cone into beaten eggs mixed with a little oyster juice or milk, then roll in fine bread crumbs.

  3. Once the coating is dry, give each croquette a second coating and fry in boiling lard 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 body of the filling.
Butter
Adds richness and helps form a smooth, flavourful sauce with the flour.
Flour
Thickens the reduced juice into a sauce that holds the filling together.
Eggs
Bind the filling and set when heated, giving the mixture structure.
Cream
Adds moisture and softness to the filling.

The step that matters

Cooling the mixture until stiff. The filling must be firm enough to shape; if it is still soft, the cones will slump and the coating will not hold. Cooling lets the starch-thickened sauce and eggs set before shaping.

Swap the marjoram

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

  1. Nutmegfits about as well
  2. Capersfits about as well
  3. Tarragonfits about as well
  4. Marjoramthe original

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