Method

1. For the mutton, sprinkle the flour onto a plate. Beat the eggs in a bowl. Sprinkle the panko breadcrumbs onto a separate plate.

2. Dust each mutton chop first in the flour, then dip it in the egg, then roll it in the breadcrumbs until completely coated. Set aside, covered, until needed.

3. For the potato and turnip gratin, bring the cream to the boil in a saucepan and season, to taste with salt and freshly ground white pepper. Remove the pan from the heat and set aside.

4. Arrange alternate layers of the potato slices and turnip slices into a large ovenproof dish, sprinkling each layer with a little of the grated garlic. Make sure you slightly overlap the slices of potato and turnip in each layer.

5. Pour over the warm cream, then transfer the dish to the oven and cook for 18-20 minutes.

6. Remove the dish from the oven and press the potato and turnip layers down using a fish slice. Return the dish to the oven and continue to cook for a further 10 minutes.

7. Repeat this process until the vegetables are tender, the cream has thickened and the top is golden-brown. Remove the dish from the oven and set aside to cool slightly.

8. Meanwhile, for the sauce gribiche, in a bowl, mix together the grated duck egg, Dijon mustard, red wine vinegar, salt, sugar, English mustard powder and smoked paprika until well combined.

9. Gradually add the olive oil in a thin stream, stirring it into the mixture until the mixture emulsifies to a paste. Stir in the cornichons, capers and parsley and season, to taste, with salt and pepper. Set aside.

10. To cook the chops, heat the vegetable oil in a large, non-stick frying pan over a medium heat. Add the breaded mutton chops, in batches if necessary, and shallow fry for 2-3 minutes on each side, or until golden-brown on both sides. Halfway through cooking, add a knob of butter and a squeeze of lemon juice to the pan and baste the chops with the mixture.

11. When the mutton chops are cooked to your liking, remove them from the pan and set aside to drain on an ovenproof plate lined with kitchen paper. Sprinkle with sea salt flakes and keep warm in an oven set to its lowest setting.

12. Chop the mutton trimmings into tiny pieces, then heat a lidded saucepan over a medium heat, add the chopped mutton trimmings and dry-fry until the fat has melted and the mutton trimmings are crisp and browned.

13. Add the onion and a pinch of salt, then cover the pan with the lid and fry for 3-4 minutes, or until the onions have softened.

14. Add the sliced cabbage, cover again with the lid and cook for 3-4 minutes, or until the cabbage is wilted and tender.

15. To serve, place two breaded mutton chops onto each serving plate with some cabbage. Spoon over a little of the sauce gribiche. Serve the potato and turnip gratin alongside.
