Get all your ingredients and equipment ready. Put a large frying pan and a large saucepan on a high heat. Fill and boil the kettle. Turn the oven on to 220°C/425°F/gas 7.
Halve the rack of lamb, season with sea salt and black pepper, then add to the frying pan with a lug of olive oil.
Scrub the potatoes and trim the carrots, then add to the large saucepan with a pinch of salt. Rip the leafy tops off the bunch of mint and save for the mint sauce. Make sure the band is still around the stalks, then add to the saucepan. Just cover with boiling water, crumble in the stock cube, and put the lid on.
Drizzle olive oil straight into the pack of neck fillet and season. Turn the racks of lamb then put the two neck fillets in the pan. Sear the ends of the meat and keep coming back to the pan and turning each piece so they brown all over.
Pull the leaves off 3 sprigs of rosemary and put into a pestle and mortar with a good pinch of salt and pepper. Peel the garlic, add to the mortar, and pound really well. Turn the lamb over. Add Dijon mustard to the mortar with a good couple of lugs of olive oil and a swig of white wine vinegar. Mix well.
Make sure all sides of the lamb are seared, then use tongs to transfer all of it to a roasting tray.
Pour away most of the fat in the pan, then put it back on a very low heat for the gravy. Spoon the dressing from the pestle and mortar over the lamb and put the vines of cherry tomatoes on top.
Move everything around until well coated in the dressing. Sprinkle with salt, then whack on the top shelf of the oven and set the timer for 14 minutes for blushing to medium meat, slightly less for rare, and more for well done. Turn the racks over halfway through.
Finely slice the bacon and put into the frying pan.
Finely chop the reserved mint leaves and add to the unwashed pestle and mortar. Pound, then add the red wine vinegar, caster sugar, a pinch of salt and 2 tablespoons of cooking water from the veg pot. Muddle together with the pestle, have a taste to check the balance, and add a tiny splash of extra virgin olive oil.
Turn the heat under the bacon right up and add the rosemary leaves. Stir in the flour, red wine and a few ladles of cooking water.
Trim all the beans and put the runner beans through a runner bean slicer or slice at an angle, 1cm thick. Cut the Savoy cabbage half in two and click off any tatty outer leaves, then discard the stalk. Cut the cabbage into thin wedges.
Add the cabbage, beans and peas to the saucepan, then stir and put the lid back on.
Turn the lamb over. If your tomatoes are colouring too much, lean the meat on top of them.
Stir in a spoonful of cooking water if needed.
Smash the bar of chocolate in its wrapping, then unwrap and put it into a small microwave-safe bowl with the vanilla paste or extract, a small pinch of salt and the milk.
Microwave on full power for 1½ minutes, leave to rest for a few seconds and stir, then microwave for 1 more minute
on full power.
Meanwhile, chop all your fruit into bite-sized chunks and wedges and pile these on a platter. Take the bowl out of the microwave and stir until all the chocolate has melted, then put the bowl on the platter and take to the table.
When the 14 minutes are up, take the lamb out of the oven and leave it to rest for 1 minute.
Drain the veg in a colander, then return them to the pan. Drizzle well with extra virgin olive oil, and add a good pinch of salt and pepper and 1 knob of butter. Squeeze over the juice of ½ a lemon and toss well. Tip on to a large serving platter and take to the table.
Taste and correct the seasoning, then pour into a gravy boat and take to the table with the mint sauce.
Cut the racks into individual chops and slice up the neck fillet. Pile on a platter. Move most of the cherry tomatoes to the platter on top of the lamb, mushing the rest into the cooking juices. Stir in a good lug of extra virgin olive oil, then drizzle over the platter and serve.
