This recipe works great as a stand-alone dish, but also as a component in Jamie’s Summery Feast from Together – see the full collection of menus here.
GET AHEAD Scrub the potatoes, chop into 3cm chunks, and parboil in a large pan of boiling salted water for 10 minutes. Drain and leave to steam dry for 2 minutes, while you use a speed-peeler to strip the peel off the lemons. In your largest roasting tray, toss the potatoes with the lemon peel and juice, 2 tablespoons of olive oil and a pinch of sea salt and black pepper. Cool, cover and refrigerate overnight.
TO SERVE Once the lamb is resting, turn the oven up to 200°C/400°F/gas 6. Roast the potatoes for 1 hour, or until beautifully golden and crisp, tossing gently halfway through.
