STEP BY STEP
Step 1: Brush the beef fillet liberally with the Dijon mustard, using a pastry brush.
Step 2: Roll the beef away from you, wrapping it tightly in the crêpe and cabbage.
Step 3: Place the wrapped beef at the top of the puff pastry. Roll the whole thing so the beef fillet is covered completely.
Step 4: Using a pastry brush, brush the pastry with egg yolk.
