Oysters Au Gratin

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 sauce

  1. Drain the oysters.

  2. In a saucepan, melt 2 tablespoons of butter over medium heat.

  3. Add 2 tablespoons of flour and stir until smooth.

  4. Gradually add 1 cup of milk, stirring until it bubbles.

  5. Stir in ½ teaspoon of salt and a pinch of cayenne pepper.

Assemble and bake

  1. Lightly grease scallop shells with butter.

  2. Place 3 or 4 oysters in each shell and cover with the cream sauce.

  3. Sprinkle with moistened fine dried bread crumbs.

  4. Bake in a 400°F (200°C) oven until golden brown and serve immediately.

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

What each ingredient does

Oysters
Are the main ingredient, cooking gently in the sauce so they stay tender.
Butter
Enriches the sauce and helps browning of the bread crumb topping.
Flour
Thickens the butter and milk into a smooth white sauce.
Milk
Forms the liquid base of the sauce, giving it body and a creamy texture.
Fine dried bread crumbs
Form a crisp, golden topping when baked.

The step that matters

Stirring the flour and milk sauce. Flour must be cooked in the melted butter and stirred while milk is added gradually, so lumps do not form. Stirring until it bubbles ensures the starch swells and thickens the sauce fully.
