Succulent stuffed roast turkey

Always choose a hen (as they are juicier than toms) that weighs at least 3 kg. Calculate the cooking time on the basis of 1 hour for every kilogram of turkey and cook at a low temperature, around 175 ºC for most of the time, then drop down to 80 ºC for the last 30 minutes. Cover the breasts with tinfoil greased with extra-virgin olive oil for the first half-hour and baste regularly with the juices.
