- 200g/7¼oz ciabatta, roughly torn
- 40g/1½oz lemon rind, grated
- 40g/1½oz capers, rinsed
- 40g/1½oz anchovies
- 40g/1½oz onions, roughly chopped
- 40g/1½oz black olives, pitted and roughly chopped
- 1 bunch parsley
- 1 bunch basil
- 2 racks of lamb, 8 bones in each
- vegetable oil, for frying
- 2 tsp Dijon mustard
- sea salt and freshly ground black pepper
- 2 butternut squash (about 650g/1lb 7oz each)
- 2 garlic cloves, crushed
- 2 lemons, zest and juice only
- 1 tbsp olive oil
- 100g/3½oz butter, 70g/2½oz melted and the rest chilled
- 1 sprig fresh thyme, leaves only
- 2-3 tbsp course-grained mustard
- 5 tbsp double cream
- sea salt and freshly ground black pepper
- Firstly, make the herb crust. Preheat the oven to 120/C248F/Gas 1. Lay the ciabatta, lemon rind, capers, anchovies, onions and olives on a baking sheet, and place them in the oven to dry out for two hours.
- Transfer the mixture to the bowl of a food processor fitted with a metal blade and blend until fine breadcrumbs form (about two minutes).
- Preheat the oven to 180C/356F/Gas 4. Season the lamb and then warm a large heavy-based frying pan. Add enough oil to cover the base and seal the lamb on each side with the fat (about two minutes).
- Brush the lamb with mustard so that it is completely covered and then roll it in the herb crust. Place the meat in a shallow baking dish and bake in the oven until medium rare, about 12 minutes, turning halfway through.
- Remove from the oven and leave to rest.
- For the butternut squash, heat the oven to 190C/375F/Gas 5. Cut the squash in half, scoop out the seeds, then peel and chop the flesh into even-sized chunks. Place in a bowl and add the garlic, lemon zest and juice, olive oil and half the melted butter.
- Toss the ingredients together then spread out in a roasting pan. Scatter over the thyme leaves and roast in the oven for about 20 minutes, until the squash feels tender when pierced with the tip of a knife.
- Scoop the roasted squash into a food processor or blender with the remaining butter, mustard, cream and seasoning. Blend to a smooth purée and serve.
- To serve, cut the lamb racks into cutlets. On each plate, arrange a few cutlets on a bed of butternut squash mixture.
