This meal always goes down a storm. It’s simple to prepare, and though the salad looks impressive, it is almost laughably easy. Serve the lamb warm, but well rested, and avoid the last minute scramble to get everything out hot. The Duchy and the rest of the Cazalets would be over the moon with it.

Serves 6
1. Preheat the oven to 150C fan/325F/gas 3. Place the lamb in a roasting tin, and make slashes into the fat. Spoon over the honey and rub it in. Pull the rosemary from the stalks, and sprinkle over the top. Pour over the oil and season with the salt. Roast in the oven for 4 hours.

2. Halve 10 of the radishes, and place in a small saucepan with the cider vinegar, salt and sugar. Bring to a simmer, turn off the heat, and leave to cool.

3. Take the lamb out of the oven, and leave to rest for 20 minutes. Pull the flesh apart with two forks (it should come away easily from the bone), and pile it up on a plate. If you’re not ready to eat yet, the lamb can be warmed through in a low oven before serving.

4. To make the gravy, place the pan with the lamb juices over a low heat and, once simmering, whisk in the flour. Cook out for a couple of minutes, then add the stock, and simmer until thick. Add the mustard, then taste and season. Sieve, and keep warm.

5. Pick the watercress and mint leaves from their stems. Put the frozen peas in a sieve and run them under cold water to defrost. Thinly slice the uncooked radishes.

6. Make the dressing by whisking together the vinegar, mustard, and pepper, then whisk in the olive oil. Toss the watercress, mint, sliced radishes and peas in the dressing. Place on a plate and top with the pickled radishes, and the goat’s cheese, torn into chunks. Serve alongside the lamb.
