Ragout of Oysters for Vol-au-vent

Ingredients

Directions

Prepare the oysters and liquor

  1. Remove all shell particles from the oysters.

  2. Strain the oyster liquor to remove sand.

Make the sauce

  1. In a thick saucepan, melt the butter and flour over medium heat until bubbling.

  2. Gradually stir in enough oyster liquor to create a sauce thick enough to coat the spoon.

  3. Season the sauce with salt, pepper, and nutmeg.

  4. Let the sauce boil once.

  5. Add the oysters and stir until their edges curl.

  6. Stir in the egg yolks, oil, and lemon juice after removing from heat.

Fill and serve

  1. Heat the vol-au-vent case in the oven if serving hot.

  2. Cut around the cover of the vol-au-vent.

  3. Remove the soft pastry inside.

  4. Fill the case with the ragout.

  5. Replace the cover.

  6. Serve immediately.

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

What each ingredient does

Oysters
Provide the main flavor and tender texture of the ragout filling.
Flour
Thickens the butter and liquor into a sauce that coats the oysters.
Butter
Adds richness and flavor, and combines with flour to form the roux base.
Oyster liquor
Supplies the liquid for the sauce and concentrates the oyster flavor.
Egg yolks
Enrich and further thicken the sauce, adding richness and body.
Lemon juice
Adds acidity that brightens the rich, creamy sauce.

The step that matters

Adding the egg yolks. Egg yolks thicken through gentle heat and can scramble if the sauce is too hot or boiling. Stirring them in after removing the pan from the heat lets them enrich the sauce smoothly.
