Step 1

Step 2
Meanwhile, heat a large non-stick frying pan over a high heat. Oil and season the steaks then sear for 11/2 minutes on each side. Remove to a warm plate, cover with foil and rest.

Step 3
Keeping the heat high, add the mushrooms to the same pan and cook, stirring, for 5 minutes until deep golden, softened and all their liquid has evaporated (add a tiny drizzle more oil if the mushrooms are sticking). Add the garlic and paprika, and fry for 2 minutes. Pour in the sherry vinegar and bubble for 1 minute until it disappears, then add the beef stock and simmer for  3 minutes. Turn down the heat and stir in the soured cream and any resting juices from the steak. Simmer for 2 minutes then season with pepper. Stir through the parsley then spoon over the steak and serve with the wedges and some watercress.
