Vinaigrette salad dressing is a super-easy marinade and since it comes in so many varieties, you always have all kinds of flavour options right at your fingertips. Roast beef is so simple to cook in the barbecue by indirect heat roasting. Our time-test results are based on a roast that was about 8-in (20 cm) long x 5-in (12.5 cm wide) x 4-in (10 cm) deep. NOTE: ‘Time-to-cook’ figures are rough guidelines only as cook time is dependent on so many factors such as barbecue and thermometer accuracy, starting temperature of roast, roast shape and cut. A good thermometer is one of your best kitchen investments
