What each ingredient does

Poached oysters: Provide the main seafood filling with a tender, delicate texture and briny flavour.
Mushroom heads: Add savoury, earthy depth and moisture to the filling once sautéed.
Sliced truffles: Contribute a strong, aromatic earthy flavour that defines the dish.
Velouté sauce: Adds a smooth, rich creaminess that moistens the filling and ties the flavours together.
Croustade shells: Form a crisp, golden edible vessel that holds the filling and contrasts with its softer contents.

The step that matters

Sautéing the mushrooms and truffles. Mushrooms release water when cooked, and if the pan is crowded or too cool they steam rather than brown. Cooking them in a hot pan until the moisture evaporates concentrates their flavour and keeps the filling from making the shells soggy.
