1. Season the beef with salt and pepper; sear all sides in hot oil until browned. Brush with English mustard and cool. 2. Finely chop mushrooms, shallots, and garlic; sauté in butter until moisture evaporates to form a dry duxelles. Cool. 3. Lay prosciutto slices overlapping on plastic wrap, spread the duxelles over prosciutto, place beef on top and roll tightly; chill to set. 4. Roll out puff pastry, wrap the beef roll completely, trim seams, and brush with beaten egg. 5. Chill briefly, then bake at 400°F (200°C) 25–35 minutes for medium-rare (internal 125–130°F/52–54°C), until pastry is golden. 6. Rest 10 minutes before slicing into thick rounds and serving.
