Roast lamb with mint sauce

Garlic and rosemary leg of lamb with sharp fresh mint sauce

Roast leg of lamb is the Easter Sunday lunch of England, when spring lamb from the South Downs and the West Country comes in, served with roast potatoes, spring greens and a jug of mint sauce. The sauce is the English twist: chopped garden mint steeped in vinegar and a little sugar, sharp enough to cut the richness of the meat. Chef's tip: make the mint sauce an hour ahead so the vinegar mellows and the mint flavour comes out.

Method

0/6 done
  1. Step 1: Take the 4 ⅜ lb bone-in leg of lamb out of the fridge 1 hour before cooking. Heat the oven to 425°F (400°F fan).

    60 min
  2. Step 2: Make 12 small cuts all over the lamb and push in slivers of 4 cloves garlic and small sprigs of 3 sprigs rosemary. Rub with 1 tbsp olive oil, 2 tsp salt and 1 tsp black pepper and sit on the 2 onions in a roasting tin.

    8 min
  3. Step 3: Roast for 20 minutes, then lower to 350°F (325°F fan) and roast about 1 hour 10 minutes more, until a probe in the thickest part reads 140°F for pink or 145°F for medium.

    90 min
  4. Step 4: Rest the lamb, loosely covered with foil, for 20 minutes; the temperature rises a few degrees. A common mistake is carving straight away, which floods the board with juice.

    20 min
  5. Step 5: For the sauce, chop the 1 oz fresh mint leaves finely with the 1 tbsp sugar (the sugar helps chop it). Put in a jug, pour over the 3 tbsp boiling water, stir, then add the 4 tbsp white wine vinegar. Taste and add a little more sugar if very sharp.

    5 min
  6. Step 6: Carve the lamb across the grain and serve with the onions, pan juices and mint sauce.

Tteokgalbi

Tteokgalbi is rib meat chopped finely, pressed back into neat slabs and grilled, so it's soft enough to eat without struggling with a bone. Two places in South Jeolla claim it: Damyang, the bamboo county, where all-beef patties come with rice steamed in bamboo tubes, and Gwangju's Songjeong district, whose restaurant street near the railway station mixes beef with pork. This home version uses minced beef and pork, seasoned with soy, garlic and pear, then brushed with a soy and honey glaze as it cooks. Serve with rice, lettuce and a few banchan; leftovers are good cold in a lunchbox. Chef's tip: slap the mince against the bowl for a few minutes; it turns sticky and the patties hold together on the grill without any breadcrumbs.

Pork souvlaki

This is a pork recipe. Walk through any Greek town after dark, from Athens to Thessaloniki, and the smell of souvlaki stands drifts down the street; cubes of pork shoulder grilled on thin skewers are the country's favourite cheap supper, eaten standing up or at a plastic-table taverna. At home you marinate the meat in lemon, olive oil, garlic and dried oregano, grill it hard and fast, and pile it on warm pitta with tzatziki, tomato and red onion. Chef's tip: cut the pork into even 2.5 cm cubes and leave a little fat on; lean loin dries out, shoulder stays juicy over high heat.

Char siu

Hanging in long glossy strips in the windows of Guangzhou's siu mei shops, char siu is the roast pork Cantonese families pick up on the way home to put on rice, noodles or into steamed buns. The outside is lacquered, sweet and a little charred at the edges; the inside stays juicy, savoury and faintly scented with five-spice. Shoulder (pork butt) is the cut to use, because its marbling keeps the strips moist through a hot oven. Marinate it overnight in the fridge, roast it the next day and eat it warm with steamed rice and blanched greens, or cold in fried rice and noodle soups. Chef's tip: save the honey for the last ten minutes; brushed on at the start it burns black long before the pork is cooked.
