I've plucked a few, but not lately. When I did, I would cut out the gobbler's sponge. It's not difficult with a very sharp blade, near impossible with a dull one; I like to use disposable blades, so sharp's never an issue. I skin the bird, fillet off the breast, and cut 1/2" steaks. Those go (one breast half each time for an adult tom, both sides for a jake) into a marinade of plenty of sliced peeled fresh ginger and garlic, with a couple of drops of Worcestershire and a tablespoon or so of olive oil. Marinate in the fridge overnight, and grill over high heat 1-2 minutes/side. We eat the whole bird fresh, don't freeze anything.
Legs, thighs, and all the meat I can trim off the carcass go into a crock pot, with just enough water to cover, on low for 24 hours. Pour off the water (save it for soup stock if into that), let it cool, and pick out all bones, sinew/tendons, cartilage, pellets, etc., so it's just pure cooked meat. Back into the crock pot with 2 tablespoons or so of olive oil, and an entire bottle of tangy barbeque sauce, for another 24 hours on low. Eat on sandwich buns, TASTY!
