I had read about brining but wasn't very keen on a big vat of salt water. Went online and found a site about the science of brining and decided on his advice to 'dry brine'. On the 23rd (earlier if a bigger turkey) I mixed thyme with maldon sea salt ( don't use fine salt). I separated skin from breast of turkey, rubbed salt into breast, rubbed salt into legs (over skin) and inside the turkey (total 7 tsp salt). Put it into the fridge in an open roasting bag ( allowed air to circulate but kept it from contaminating other food).
The past two years, despite basting and following Delia and then Nigella,my turkey was dry. This year it was brilliantly moist and I will be dry brining from now on. Only downside is that because brining keeps the moisture in the turkey, there was little (very little) stock for the gravy, but that is easily dealt with. The meat was also slightly more tough, but again, better than dry. Who says old birds can't learn new tricks.
Happy New Year.
