For all joints, use the following times based on the weight of your joint:
Medium: 30 minutes per 450g (1 lb), plus 30 minutes
Well done: 35 minutes per 450g (1 lb), plus 35 minutes
If you prefer to use a meat thermometer, follow these temperatures, ensuring you take the temperature in the centre of the joint and away from any bone:
Medium: 75-80 degrees C
Well done: 80-85 degrees C
Fast fillet roasts
Fillets are quick enough to roast for a midweek supper, and delicious enough to roast anytime! Simply allow 25-30 minutes at 180 C for a fillet roast. For an easy flavour boost, baste during the last 15 minutes of cooking with BBQ sauce; a mix of Dijon mustard and honey; a combination of marmalade and horseradish sauce; or a drizzle of olive oil, lemon juice and oregano.
