Salt and pepper the beef, ensuring to cover every side.
Sear the beef quickly on a hot pan, then brush mustard on it and let it rest.
Make the sauce by melting unsalted butter, adding blueberry wine, beef stock, herbs, and reducing until thickened.
Blend mushrooms into a paste with garlic, nuts, salt, and breadcrumbs.
Wrap the beef with ham and mushroom paste, then chill in the fridge for at least 10 minutes.
Prepare the puff pastry, wrap the beef tightly, and chill for another 10 minutes.
Decorate the pastry with lattice strips, brush with egg wash, and bake at 210°C (410°F) for 25 minutes.
Serve the Japanese Beef Wellington with the prepared sauce. Enjoy!
