I have a frozen turkey crown sitting in my freezer and just want to check I'm not going to kill anyone with it.
So...
Defrost (24 hours in fridge?)
Brine in bucket (48 hours in bucket outside?)
Bring to room temperature (a few?? hours out of brine and in the kitchen?)
Cook.
That seems like a long time for it to potentially turn into a food-poisoning monster...
