without a fan (gas mark 8).
Choose a large, heavy based roasting tray, ideally with deep
sides and handles for easy movement.
Season with good quality fine sea salt just prior to cooking.
Make a trivet by roughly hopping equal amounts of onion. carrot and

celery) plus a bay leaf, sprig of rosemary and a few black
peppercorns.
Place the joint onto the trivet which should line the base of

Place in the centre of the oven and roast for 20 minutes, then
reduce the temperature to 160C or 180C without a fan (gas mark
4).
Continue roasting for 12-15 minutes per 500g reaching a core
temperature of 56C,
Remove from the oven, put onto a clean tray and keep warm by
covering with a sheet of foil.
Rest for a minimum of 20 minutes before carving, leaving the
roasted vegetables in the tray for the gravy.
For the gravy, make up 500ml of chicken or lamb stock, then
deglaze roasting tray with the stock stirring in all the
caramelised juices from the tray. Next, pass through a fine sieve
pushing all the juices from the vegetables into a clean saucepan.
Bring to a simmer and thicken if required by whisking in a teaspoon
of cornflour mixed with a little cold water and reduce till you
reach a rich, glossy gravy.
