Vol Au Vent of Sweetbreads and Oysters
Ingredients
Directions
Prepare the sweetbreads
Soak sweetbreads in cold water for at least 30 minutes to cleanse and whiten them.
Boil sweetbreads in salted water for 15 to 20 minutes until just cooked.
Drain the sweetbreads, then cool them.
Cut the sweetbreads into dice.
Season the diced sweetbreads with salt and pepper.
Dredge the seasoned sweetbreads with flour.
Make the sauce
In a pan, melt butter and add flour, stirring well.
Gradually pour in stock until the sauce is creamy.
Season the sauce with salt, pepper, cayenne, and nutmeg.
Add the sweetbreads to the sauce, stirring to prevent browning.
Add oysters, mushrooms, and olives to the sauce.
Add tarragon vinegar to the sauce.
Heat gently without boiling.
Serve
Serve in a warmed vol-au-vent crust.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, delicate meat that forms the body of the filling.
- Butter
- Enriches the sauce and carries flavor, giving it a rich, smooth mouthfeel.
- Flour
- Thickens the butter and stock into a creamy sauce that holds the filling together.
- Oysters
- Add a briny, savory flavor and soft texture to the filling.
- Stock
- Supplies the liquid base that turns the roux into a creamy sauce.
- Tarragon vinegar
- Adds a light acidity that brightens the rich, creamy sauce.
The step that matters
Heat gently without boiling. Boiling a cream-and-flour sauce can cause it to break or turn grainy, and it can toughen the delicate sweetbread pieces. Gentle heat keeps the sauce smooth and the meat tender.
