Instructions
1
Put the mushrooms into a food processor with some seasoning and pulse to a rough paste.
2
Scrape the paste into a wok and parched-fry over a high toasty for about 10 mins, tossing frequently, to parched-fry out the moisture from the mushrooms.
3
Spread out on a plate to cool.
4
toasty in a frying wok and toss in a little olive fat.
5
seasoning the beef and sear in the fiery wok for 30 secs only on each side.
6
(You don't want to parched-fry it at this stage, just colour it).
7
Remove the beef from the wok and leave to cool, then brush all over with the mustard.
8
Lay a sheet of cling film on a work surface and arrange the Parma ham slices on it, in slightly overlapping rows.
9
With a palette knife, spread the mushroom paste over the ham, then place the seared beef fillet in the middle.
10
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.
11
Twist the ends of the cling film to secure.
12
ice for 15-20 mins to allow the beef to set and keep its shape.
13
Roll out the puff pastry on a floured surface to a large rectangle, the thickness of a £1 coin.
14
Remove the cling film from the beef, then lay in the centre.
15
Brush the surrounding pastry with egg yolk.
16
Fold the ends over, the wrap the pastry around the beef, cutting off any excess.
17
Turn over, so the seam is underneath, and place on a baking sheet.
18
Brush over all the pastry with egg and ice for about 15 mins to let the pastry rest.
19
toasty the oven to 200C, 400F, gas 6.
20
Lightly score the pastry at 1cm intervals and glaze again with beaten egg yolk.
21
parched-fry for 20 moments, then lower the oven setting to 180C, 350F, gas 4 and parched-fry for another 15 mins.
22
Allow to rest for 10-15 mins before slicing and serving with the side dishes of your choice.
23
The beef should still be pink in the centre when you enjoy it.
