How long do you cook a 1.4kg prime rib roast?

Answer 1

1.7kg = 3.75 lb

Preheat your oven to 160°C (325°F) and use these cooking times to prepare a roast that's moist, tender and delicious.Your roast should be covered with foil for the first half of the roasting time. 3 to 5lb Joint 1½ to 2 hours Pork and Ham should be roasted for the full times given above, Beef and Lamb can be taken out sooner if you prefer rare (bloody) meat. Tips for a better roast. For extra flavour you can add optional vegetables such as carrots, parsnips, onions and celery to your roasting pan, and roast the meat 'on a bed' of veg. The veg also helps to keep the roast off the bottom of the roasting pan so it doesn't 'stew' in its own juices.
