Chargrilled pork fillet with apple sauce
Trim the pork fillets of any fat, and cut into 1cm/1⁄2in thick rounds before placing in a bowl. Mix together half of the the cider with the sugar, mustard, garlic, rosemary sprigs, oil, half of the lemon zest and 1 tablespoon of the lemon juice. Pour over the pork, and rub all over the meat. Cover and chill until needed.
To make the sauce, put the remaining lemon zest in a small mixing bowl with 2 tablespoons lemon juice, the remaining cider, the sultanas and thyme leaves. Peel, core and finely dice the apples, one at a time, mixing them in as you go. Season with salt and pepper, and set aside.
Preheat the grill until hot. Remove the meat from its marinade, and season with salt and pepper. Cook the meat under the grill for 3 minutes per side, removing as soon as it is just cooked through, so that it retains its tenderness. Serve with the apple sauce.
