Once you pull the bird at 155°F, it will continue cooking (carryover heat) for another 5 to 10 minutes. That final temp will settle around 160°F. Perfect.
Let it rest for at least 15 minutes under loose foil. I know, I know—you want to carve it now. Resist. The juices are partying inside the meat. If you cut early, they run out onto the cutting board instead of your mouth.
Side note: I once ignored this rule because I was "starving." I ended up with pale, dry slices and a puddle of sadness. Don't be me. Be better.
Brining: your secret weapon
Wild turkey is skinny. To keep it from drying out, you need moisture inside the cells. A wet brine (salt, sugar, water, maybe some apple cider) for 12-24 hours does magic. It breaks down proteins so they hold water.
No time for that? A dry brine works too. Rub salt all over (including under the skin) and leave it uncovered in the fridge overnight. The skin gets crispy, the meat stays tender.
Dry brining also means you get that dramatic, golden, shatteringly crisp skin everyone fights over. Win-win.
