Turkey can be a dry meat, so the key is to try and keep the turkey moist throughout the cooking process.
The first step is to coat the bird in melted butter. I find that the easiest way to do this is to melt the butter in a microwave and to use a brush to apply to the bird. If you don't melt the butter, and the bird and/or the butter are cold, this becomes a pretty impossible task!
The next step is to cover the crown of the bird in streaky bacon, which will release more fat over the turkey as it cooks. Finally, I like to create a turkey tent with a cork and foil. This helps to retain moisture, promotes even cooking, and prevents the surface from browning too quickly and drying out.
