Choose a size which is enough for you and your guests.

Many people order a bird which is too large and takes longer to cook. Ideally, leftovers should be just that. A bird size of 12lbs feeds about ten people.

The weights below will give you plenty on Christmas Day and enough for some inventive cooking in the days that follow.

  • 5kg (11lb) 6-8 people
  • 6kg (13lb) 8-10 people
  • 7kg (15lb) 10-12 people
  • 8kg (17.5lb) 14-16 people
  • 9kg (20lb) 18-22 people

Make a note of the weight as you will need this to calculate cooking time.

First calculate your cooking time...

For 5-7kg total weight allow 30 minutes per kg. Example: 6kg = 180mins

For every additional kilo, above 7kg, allow 20 minutes per kilo. Example: 9kg turkey = 7kg x 30 mins plus 2kg x 20 mins = 250 mins.

* And remember: If the turkey is stuffed inside, calculate the cooking time based on the total weight of bird and stuffing. Weigh the stuffing separately, as few domestic scales or balances can cope with huge weights.

Six steps to a sumptuous Christmas dinner:

  1. Remove your bird from the fridge about two hours before cooking so it is at room temperature for stuffing. To stuff your bird use your hands to push some of the stuffing into the neck end. Put the remainder in the body cavity.
  2. Check the weight of your turkey and calculate your cooking times. Preheat the oven to 190 °C (375 ° F) gas mark five. Oven temperatures vary so check your manufacturer’s handbook.
  3. Mix some freshly chopped herbs with butter and apply this to the turkey breast.
  4. Cover your bird loosely in foil and place in a roasting tin. When your oven is up to temperature put the turkey on the bottom shelf. You could try putting it upside down on its breast, so the juices from the back and legs run into the drier breast meat and keep it moist. Cooking a turkey uncovered and upside down will reduce the cooking time, so check on things with 30–40 minutes to go.
  5. Regularly baste to retain moisture and remove the foil for the last 40 minutes of cooking, so the skin turns a golden brown.
  6. Is it cooked? Pierce the thickest part of the thigh with a skewer. If the juices run golden and clear it is ready, if they run pink continue cooking. Once fully cooked, allow excess juice to run out of the turkey then carefully transfer to a warm dish. Allow to ‘rest’ for around 30 minutes before carving.
