How to defrost a turkey
It is important that you allow enough time for your turkey to defrost. If it is not fully defrosted at the start of cooking it will not cook properly, and your cooking times will not be accurate.
When defrosting in the fridge (recommended) , allow 8-12 hours per kg. Alternatively, in a cool room (which must stay below 17.5c) allow 3-4 hours per kg.
Make sure to place your turkey in a roasting tray large enough to catch the drip from the thawing meat. This will help avoid cross contamination in your kitchen and help to stop the spread of bacteria.
