ASDA part of the Wal-Mart family

• 1 leg of lamb, 1.3kg, boneless
• 2 or 3 fresh Asda rosemary stems, leaves picked off
• 2 cloves garlic, peeled and cut into thin slivers
• 1⁄2 50g can anchovy fillets, drained and cut into 1cm pieces (optional)

1 Preheat the oven to 190C/Gas 5. Using a sharp knife, make small incisions all over the skin of the lamb. Into each slit, insert two leaves of rosemary, a sliver of garlic and a piece of anchovy. Season well – with pepper only if you’re using anchovies because they’ll provide enough salt.

2 Put the lamb in a roasting tin, and cook in the oven for 25 minutes per 450g, plus 25 minutes – about 1 hour 40 minutes for a 1.3kg leg. Put the lamb on a plate, cover with foil and leave to rest for 15 minutes before carving.
