Beef Carpaccio with Balsamic, Walnuts and Blue Cheese

Thinly slice the beef and place between two pieces of plastic wrap. Flatten gently with a rolling pin. Put a tablespoon each of olive oil and balsamic vinegar on a large platter and swirl together. Top with a single layer of beef and season with sea salt and freshly ground pepper. Cover with another piece of plastic wrap and repeat the layering of olive oil, balsamic, beef and seasoning to form as many layers as required. Leave for at least 1 hour but refrigerate if leaving for longer. The beef can be prepared several hours ahead. Remove from the fridge 30 minutes before serving.

To serve: Arrange the beef in a single layer on serving plates. Scatter the blue cheese, walnuts and rocket over the beef and serve with crusty bread.
