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.
Remove sweetbreads from the pot, drain them, and cool them.
Cut the sweetbreads into dice.
Season the diced sweetbreads with salt and pepper, and dredge with flour.
Make the sauce
Melt butter in a pan.
Add flour to the melted butter and stir well.
Gradually pour in stock until the sauce reaches a creamy consistency.
Season the sauce with salt, pepper, cayenne, and nutmeg.
Combine and serve
Add the seasoned sweetbreads to the sauce, stirring to prevent browning.
Add oysters, mushrooms, olives, and tarragon vinegar to the sauce.
Stir and heat the mixture without boiling.
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 with fat, giving it a smooth, rich mouthfeel.
- Flour
- Thickens the butter and stock into a creamy sauce that coats the filling.
- Stock
- Forms the liquid base of the sauce, carrying its flavour and body.
- Oysters
- Add a briny, savoury flavour and soft texture to the filling.
- Olives
- Add a salty, briny accent that contrasts with the rich sauce.
The step that matters
Stir and heat the mixture without boiling. Boiling a flour-thickened sauce can break its smooth texture and toughen delicate proteins in the oysters and sweetbreads, so gentle heat keeps the filling tender.
