Ragout of Oysters for Vol-au-vent
Ingredients
Directions
Prepare the oysters
Remove all shell particles from the oysters and strain their liquor to remove sand.
Make the sauce
In a thick saucepan, melt the butter and flour over medium heat until bubbling.
Gradually stir in enough oyster liquor to create a sauce thick enough to coat the spoon.
Season the sauce with salt, pepper, and a pinch of grated nutmeg, then bring to a boil.
Finish and serve
Add the oysters and stir until their edges curl.
For a richer sauce, stir in the egg yolks off the heat, then add oil and lemon juice gradually.
Heat the vol-au-vent case in the oven if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main body and briny flavour of the ragout.
- Flour
- Thickens the butter and oyster liquor into a smooth sauce that coats the oysters.
- Butter
- Carries flavour and enriches the sauce, and cooks with the flour to form the roux base.
- Egg yolks
- Add richness and body to the sauce when stirred in off the heat.
The step that matters
Adding the egg yolks. If the yolks are stirred into a hot sauce, they can scramble and curdle. Removing the pan from the heat before adding them lets the yolks thicken the sauce gently and smoothly.
