Method
1. Prepare the Beef
-
Pat the beef dry and season generously.

Heat oil or butter in a heavy pan until very hot.

Sear on all sides until well browned:

Fillet: 1–2 minutes per side
-
Sirloin: 2–3 minutes per side
-
Rump: 3 minutes per side
-
-
Brush with mustard while still warm, then leave to cool completely.
Tip: Cooling fully is essential to keep the pastry crisp and prevent splitting.
2. Make the Duxelles
-
Sauté shallots in butter for 2 minutes, add garlic.
-
Add mushrooms and herbs, cooking until all liquid has evaporated and the mixture becomes paste-like (10–15 minutes).
-
Season and allow to cool.
3. Wrap with Prosciutto
-
Lay cling film on a work surface.
-
Arrange prosciutto slightly overlapping to form a rectangle.
-
Spread the duxelles across the surface.
-
Place beef in the centre and roll tightly to form a firm, even log.
-
Chill for 30–60 minutes.
4. Add the Pastry
-
Roll out pastry and place the beef in the centre.
-
Wrap neatly, trim excess and seal edges.
-
Brush with egg yolk and score lightly for decoration.
-
Chill for another 30 minutes.
