Beef Wellington

Put the mushrooms into a food processor with some seasoning and pulse to a rough paste. Scrape the paste into a pan and cook over a high heat for about 10 mins, tossing frequently, to cook out the moisture from the mushrooms. Spread out on a plate to cool.

Heat in a frying pan and add a little olive oil. Season the beef and sear in the hot pan for 30 secs only on each side. (You don't want to cook it at this stage, just colour it). Remove the beef from the pan and leave to cool, then brush all over with the mustard.

Lay a sheet of cling film on a work surface and arrange the Parma ham slices on it, in slightly overlapping rows. With a palette knife, spread the mushroom paste over the ham, then place the seared beef fillet in the middle. Keeping a tight hold of the cling film from the edge, neatly roll the Parma ham and mushrooms around the beef to form a tight barrel shape. Twist the ends of the cling film to secure. Chill for 15-20 mins to allow the beef to set and keep its shape.
