This dish is a variation of the Beef Wellington in a way. It is, however, fabulous for dinner parties and is always enjoyed by all.
Serves 4
The beef roll:
450 g/1 lb mixed mushrooms
salt
8 green asparagus, trimmed and blanched in salted water
8-10 slices prosciutto
2 tablespoons/30 ml olive oil
700 g/1.6 lbs beef fillet, trimmed
2 tablespoons/30 ml wholegrain mustard
450 g/1 lb puff pastry
1 eggs, whisked, for glazing
The sauce:
1 cup/250 ml red wine
1½ cup/375 ml beef stock, heated
the reserved mushroom paste
½ cup/125 ml full cream
The cauliflower cream:
1 tablespoon/15 ml butter
1 medium size cauliflower, cut into small pieces
1 cup/250 ml full cream
1 tablespoon/15 ml crème fraîche
¼ teaspoon nutmeg, grated
2 teaspoons/10 ml lemon juice
salt and freshly ground black pepper to taste
The peas:
2 cups/500 ml peas (fresh or frozen and defrosted)
1 tablespoon/15 ml butter
1 tablespoon/15 ml sugar
salt
2 teaspoons/10 ml mint, finely chopped
- In a food processor, chop the mushrooms until a rough paste forms. Transform to a non-stick frying pan and dry fry the mushrooms until all its natural moisture has evaporated. Season and put aside to cool.
- Cut the beef horizontally but not right through. Stop about 3 cm/1¼ in away from the edge.
- Fold the fillet open like a book and place between two sheets of plastic film.
- With a mallet, lightly bash the meat all over to get an even thickness.
- Sprinkle with salt on the cut side then spread the cooked mushrooms evenly all over (reserving 2 tablespoons/30 ml for the sauce) , leaving a small space on the edges all round.
- Cut the asparagus tips off and set aside.
- Place the stems in the center horizontally, then roll up the beef. Secure with a skewer or toothpicks.
- Heat the olive oil in a frying pan until very hot and quickly sear the steak all round.
- Set aside to cool.
- When the meat has cooled almost completely, roll out a large piece of plastic film and place the prosciutto alongside each other to more or less the size you will need to cover the fillet all round.
- Remove the skewers or toothpicks from the meat, then spread mustard all over the outside.
- Place the meat in the center of the prosciutto and with the help of the plastic film, roll the fillet with the prosciutto into a neat roll.
- Twist the ends of the plastic film to prevent it from splitting open and refrigerate for at least 20 minutes.
- Preheat the oven to 200°C/390°F and grease a baking tray.
- When ready to cook, roll out the pastry into a rectangle, unwrap the beef carefully and place in the center of the puff pastry.
- Brush the pastry edges all round with the egg wash then fold it over the beef and seal.
- Trim the ends of the pastry and with the help of the egg wash, seal the ends neatly.
- Paint the pastry all over with the egg wash and lift the roll onto the baking tray.
- Refrigerate for about 15 minutes.
- Remove the roll from the refrigerator and brush again with the egg wash.
- Lightly score the top of the pastry and place in the oven to bake for 15 minutes.
- Turn the baking pan around and lower the heat to 180°C/356°F. Bake for 10 minutes more.
- Remove from the oven and let it rest for at least 15 minutes before slicing.
- Heat the pan in which you seared the beef and deglaze it with the red wine.
- When all the alcohol has evaporated and the pan is nearly dry, add the stock and reduce to half.
- Add the mushroom paste and cook until the sauce has reduced to a half.
- Stir in the cream and let it cook until it thickens.
- Strain, season with salt and freshly ground black pepper and pour back into the pan to keep warm.
- After the beef roll has rested and you are ready to cut it, pour the juices that leaked out of the roll into the sauce and mix.
- Meanwhile, for the cauliflower, bring water in a saucepan to the boil and add the butter and cauliflower. (The water should only come halfway up the cauliflower).
- Cook until the cauliflower is tender. (The water should have reduced down to about half).
- Pour all the content of the saucepan (and the water) into a food processor and blend until smooth. (It should be the consistency of thick whipped cream).
- Add the cream, crème fraîche, nutmeg, salt and pepper and blend until smooth.
- Add 1 teaspoon/5 ml of lemon juice and taste, then add more if required.
- Pour back into the saucepan and keep warm until ready to serve.
- Melt the butter in a saucepan and add the peas, a pinch of salt and 1 teaspoon/5 ml of sugar.
- Let it heat through over low heat until the sugar has melted.
- Add the chopped mint and set aside in a warm place until ready to serve.
