    Pre heat oven to 180 degrees.

    Lightly rub the olive oil all over the steak. Season on both sides with salt and pepper.
    Heat a heavy based pan to a medium heat and seal on both sides until nicely golden brown, When caramelised all over transfer to a roasting tray and cook for 6 to 8 minutes depending on the thickness of the steak. Remove from the oven and allow to rest for at least the same amount of cooking time. All of the resting juices left over should be added to the sauce. When ready to serve heat your steak back up in a very hot oven.


    Place the shallots in a heat proof bowl. Cover with boiling water and leave for 5 minutes. This will make them easy to peel. When peeling the shallots be sure to leave the root end attached as this will keep them together while cooking.

    Melt half of the butter. When foaming add the shallots to the pan. Using a pair of tongs turn the shallots as they begin to colour. Every time the butter drops down from foaming add another knob. Don't be tempted to add to much butter in one go, you want to keep it foaming at all times. After around 8 to 10 minutes and nicely coloured all over add the thyme followed by balsamic vinegar. Immediately cover with tin foil and place in the oven to cook for 5 minutes.

    Remove the pan from the oven and spoon out the shallots 1 by 1 onto a clean roasting tray. Don't try and save time at this point by tipping the shallots out in 1 go as they will lose their shape!

    Reheat in the oven when ready to serve.


    Remove any outer tough leaves from the cabbage.

    Remove the central white stalk from the cabbage. Cut the leaves into neat batons of equal size. Blanch in boiling salted water. Drain and season lightly with salt and pepper.


    Preheat the oven to 180'C.

    Peel the potatoes and slice into 2mm thick slices using a mandoline or sharp knife. Peel and finely dice the garlic. Peel and finely grate the horseradish. Roughly chop the parsley.

    In a large saucepan, bring the milk and double cream to the boil. Stir in the garlic and grated horseradish to the pan and cook for one minute. Add the potatoes to the pan and season with salt. Bring back to the boil and then add half of the the chopped parsley. Remove the potatoes from the pan using a slotted spoon and place in a deep baking tray. Spoon over any remaining cream and place the tray in the oven and cook for 40 minutes until the top is golden brown. Check the potatoes are cooked using a skewer.


    Peel and finely slice the shallots. and garlic. Add to a pan along with the bay leaf and red wine. Reduce by half. Add the veal stock and reduce down to the desired consistency.

    Pass through a sieve and rub a knob of butter across the surface,this will help prevent a skin from forming.

  • 6. TO PLATE

    Make sure everything is hot.

    Arrange a neat pile of cabbage in the center of the plate. Place the steak/shallot confit on top. Spoon 3 shallots around the meat, finish with a generous amount of sauce. Serve the potatoes in a side bowl to avoid over crowding the plate.

Chef's tip

«The thickness of the meat will determine how long you should cook it for. For example a piece of meat an inch thick will only need to be pan fried and rested where as a piece 2 inches thick will need to go through an oven and rested»
