To make the lamb stock, put the lamb bones in a large saucepan and cook over a medium-high heat for 8-10 minutes until lightly browned, turning every now and then. Add the onion, celery, carrot, thyme and bay leaf to the pan.
Pour over the water and bring to a gentle simmer. Skim off any foam that floats to the surface. Leave to bubble gently for 45 minutes. Remove from the heat and strain through a fine sieve into a clean jug; leave to stand. Spoon off any fat that rises to the surface after the stock has cooled.
While the stock is simmering, make the stuffing. Cut the crusts off the bread and cut the rest into roughly 1 cm cubes – you’ll need around 75g. Trim the leek, dropping the leek trimmings into the stock if you like, and finely slice. Finely chop the onion and crush the garlic.
Heat 2 tbsp of the oil in a large non-stick frying pan and fry the bread for 3-4 minutes until golden. Tip into a large mixing bowl and return the pan to a low heat. Add the remaining oil and stir in the leek, onion and garlic. Cook for 2-3 minutes, stirring until softened but not coloured. Tip the sautéed vegetables into the pan with the bread and add the capers, lemon zest, mint, parsley, salt and plenty of freshly ground black pepper. Stir well and set aside to cool.
Place the lamb on a chopping bard, skin side down, and trim off any hard lumps of fat or sinew if your butcher hasn’t already done so. Cover with a large sheet of cling film. Take a sturdy rolling pin and bash the thickest parts of the meat to flatten them until the meat is around 3 thick all over.
If necessary, trim off any untidy bits and use them to patch the lamb where the meat is more scarce. You want it to look like a pretty even rectangle of meat when you’ve finished, so take care to keep it neat. Season with salt and pepper.
Spoon the stuffing across the centre of the lamb, from one short side to the other. Lift the two long sides and wrap over the stuffing to fully enclose. Cut 7-8 lengths of kitchen string, each long enough to wrap around the lamb and place at 3cm intervals underneath.
Tie the string very tightly, starting at each end, then in the middle and finally the places in between. This should help prevent the stuffing bulging out but if it does, simply push back into the parcel. Tie another piece of string around the lamb from one end to the other to hold the whole parcel together. Trim off all the excess string.
Weigh the lamb and place in a small roasting tin. You can chill it for several hours at this point but don’t forget to return to room temperature for 30 minutes before cooking. Preheat the oven to 200C/fan oven 180C/Gas 6. Rub the lamb all over with a little oil. Season with flaked sea salt and freshly ground black pepper. Roast in the centre of the oven for 20 minutes per 500g. The lamb will take about an hour and a quarter. (Cook the boulangere potatoes on the shelf underneath the lamb.)
While the lamb is cooking, prepare the mint sauce. Put the chopped mint leaves and sugar in a small bowl and bruise with the back of a spoon for a minute to extract the flavour. Stir in the white wine vinegar. Add a little olive oil. The dressing should look fairly thick, but spoonable when you’ve finished. Set aside.
Take the lamb out of the oven and put on a board. Cover with a piece of foil and a couple of dry tea towels and leave to rest for 15 minutes while the sauce is finished. Spoon off as much fat as you can from the tin, leaving all the lovely, golden brown juices. Place on the hob. Stir in the flour with a wooden spoon and cook for a few seconds.
Slowly start adding 300ml of the reserved lamb stock, stirring constantly until it is all incorporated. Stir in the red currant jelly and the mint sprig and bring to a gentle simmer. Cook for 10 minutes, stirring occasionally and season to taste. Stir in any juices from the resting meat. Pass through a fine sieve into a warmed jug.
Trim the ends off the lamb parcel and remove the string. (Keep the end bits for a cold lamb sandwich.) Carve the lamb into thick slices. Place rounds of hot boulangere potatoes in the centre of six deep warmed plates. Top with sautéed chard or spinach and then a slice of the lamb. Pour the jus around the lamb and dot with a little of the mint sauce. Garnish with a few tiny mint leaves and serve.
