To Cook Rare: 2½ minutes on each side
To Cook Medium: 4 minutes on each side
To Cook Well Done: 6 minutes on each side
- 2 lean fillet steaks
- 25g unsalted butter
- 1 tablespoon olive oil
- 1 large shallot, peeled and finely chopped
- 50g mushrooms (wild, if in season), halved
- 3 tablespoons Armagnac or brandy
- 300ml good, hot beef stock
- 2 sprigs fresh thyme leaves
- Fresh redcurrants, to garnish
For the potato slices:
- 375g small waxy potatoes, peeled and left whole
- 25g unsalted butter, melted
- 150ml good, hot vegetable stock
- Preheat the oven to 200°C, 180°C Fan, Gas Mark 6.
- To prepare the potato slices; boil the potatoes in salted water for 10-15 minutes. Drain and cool slightly. When cool enough to handle slice to the thickness of a pound coin and transfer to a large bowl.
- Add the melted butter, season and toss gently. On a foil lined shallow baking tray or roasting dish arrange four 8cm cakes in a single layer of overlapping slices. Pour over the stock and bake for 15-20 minutes or until tender and most of the stock has evaporated.
- Meanwhile, melt half of the remaining butter with the oil in a non-stick griddle or frying pan. Season the fillets and cook according to your preference. Remove, transfer to a warm plate, cover and set aside to rest.
- Add the shallots and mushrooms to the same pan. Add the Armagnac or brandy. Cook for a further minute then add the stock and thyme. Bring to the boil, reduce the heat and simmer for 4-5 minutes or until reduced by half. Whisk the remaining butter into the sauce. Remove the thyme sprigs.
- Arrange the potato cakes on a warm plate, top with the beef and spoon over the sauce. Garnish with the redcurrants and serve with seasonal vegetables.
