Buy whole, fresh or frozen. Fresh is best. If buying frozen, check the packaging to ensure that it hasn't been injected with fatty substances used to keep the meat moist.
Fresh turkeys should be stored in the refrigerator, in the back on a lower shelf for no more than 2-3 days.
A whole frozen turkey in its original packaging will store for up to 9 months. Once thawed they will keep in the refrigerator for up to 4 days.
Tips & Tricks:
To keep the turkey moist soak a double layer of muslin in light olive oil or grapeseed oil and drape it over the bird while it roasts. Remove the cloth 30 minutes before taking the bird from the oven for a crispy skin.
Allow 500g per person when buying a whole turkey - this will give you some leftovers. Make sure the turkey you buy fits into the fridge, roasting pan and oven.
