- A challenge
- Serves 6
- a good beef fillet (preferably Aberdeen Angus) of around 1kg/2lb 4oz
- 3 tbsp olive oil
- 250g/9oz chestnut mushroom, include some wild ones if you like
- 50g/2oz butter
- 1 large sprig fresh thyme
- 100ml/3.5 fl oz dry white wine
- 12 slices prosciutto
- 500g/1lb 2oz pack puff pastry, thawed if frozen
- a little flour, for dusting
- 2 egg yolks beaten with 1 tsp water
- STEP 1
Heat oven to 220C/fan 200C/gas 7.
- STEP 2
- STEP 3
- STEP 4
Heat 2 tbsp of the olive oil and 50g butter in a large pan and fry the mushrooms on a medium heat, with 1 large sprig fresh thyme, for about 10 mins stirring often, until you have a softened mixture.
- STEP 5
Season the mushroom mixture, pour over 100ml dry white wine and cook for about 10 mins until all the wine has been absorbed. The mixture should hold its shape when stirred.
- STEP 6
Remove the mushroom duxelle from the pan to cool and discard the thyme.
- STEP 7
Overlap two pieces of cling film over a large chopping board. Lay 12 slices prosciutto on the cling film, slightly overlapping, in a double row.
- STEP 8
Spread half the duxelles over the prosciutto, then sit the fillet on it and spread the remaining duxelles over.
- STEP 9
Use the cling film’s edges to draw the prosciutto around the fillet, then roll it into a sausage shape, twisting the ends of cling film to tighten it as you go.
- STEP 10
Chill the fillet while you roll out the pastry.
- STEP 11
- STEP 12
Roll out the remainder of the 500g pack of puff pastry to about 28 x 36cm.
- STEP 13
Unravel the fillet from the cling film and sit it in the centre of the smaller strip of pastry.
- STEP 14
Beat the 2 egg yolks with 1 tsp water and brush the pastry’s edges, and the top and sides of the wrapped fillet.
- STEP 15
Using a rolling pin, carefully lift and drape the larger piece of pastry over the fillet, pressing well into the sides.
- STEP 16
Trim the joins to about a 4cm rim. Seal the rim with the edge of a fork or spoon handle.
- STEP 17
Glaze all over with more egg yolk and, using the back of a knife, mark the beef Wellington with long diagonal lines taking care not to cut into the pastry.
- STEP 18
Chill for at least 30 mins and up to 24 hrs. Heat oven to 200C/fan 180C/gas 6.
- STEP 19
Brush the Wellington with a little more egg yolk and cook until golden and crisp – 20-25 mins for medium-rare beef, 30 mins for medium. Allow to stand for 10 mins before serving in thick slices.
