Croustade of Oysters

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the filling

  1. Scald the oysters in their own liquor.

  2. Combine the liquor with equal parts velouté and anchovy sauces, and reduce until thick.

  3. Add the oysters to the sauce.

Assemble and bake

  1. Fill fancy croustades with the mixture.

  2. Sprinkle the tops with grated Parmesan cheese and breadcrumbs.

  3. Bake in a 400°F (200°C) oven until golden brown.

Serve

  1. Serve on hot plates with paper doilies.

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

What each ingredient does

Oysters
Provide the main seafood flavor and tender texture when gently scalded in the sauce.
Velouté sauce
Forms the thick, creamy base that holds the filling together.
Anchovy sauce
Adds a salty, savory depth that enriches the sauce.
Grated parmesan cheese
Melts and browns on top, adding a savory, golden crust.
Breadcrumbs
Create a crisp, golden topping during baking.

The step that matters

Reduce the sauce until thick. The liquor, velouté and anchovy sauce must be reduced enough to thicken before the oysters are added. If the sauce stays thin, it will run out of the croustades and turn the filling watery during baking.
