Except for the liver, eat 'em! They need long cooking so I do simmer them with the neck and some celery & herbs first, and then use that stock for the gravy. The liver is thrown out or cooked for any animals in the house that like it, which currently is zero.
My Dad used to just fry them up and eat them in a sandwich, which completely horrified the rest of us. My Brother in Law feeds them to the dogs. Cajun-style Blackened Chicken Livers are great, but other than that, I’ve never found any use for them.
Celery, onions, butter, and liver into a frying pan, then added to a bunch o’ingredients for stuffing. Everything else goes to the puppies, who love, love, love, LOVE when I cook for Thanksgiving.
We leave them outside, far from the house, for the bears. But not in the roasting pan any more, not since one stole it (don’t worry, we followed the paw prints to find it, so it’s not out there still).
I throw it out. You can buy a huge amount of the stuff very cheaply. For just a turkey breast, you might try doing it on the BBQ, or possibly braising it. I’ve never done just a turkey breast by itself.
Make a sausage meat out of anything you like, with herbs and some bread crumbs, and rendered duck fat if you have it. Saturate with cream, and stuff everywhere under the skin (except the back). Use a smooth spoon to help seperate the skin to get back under the legs and wings. Yell ‘help help it’s still alive’ while your hand is shoved up under the skin. Then wiggle a leg when they turn to look. Cook on one side for a while, then the other, then upright to finish. Use the cheesecloth with olive oil to get a fabulous looking golden brown skin. Stuff the cavity after cooking or it will take too long.
My mom used to cook the gizzard separately (and let the family, except me - yuck, fight over it) and then squish up the liver and put it in the stuffing. Her stuffing beats my in-laws by a mile, but they are cooking for vegetarians as well, so no meat products in the stuffing, and nothing gets stuffed with it.
My heart breaks at the idea of giving the liver to the dog. Or indeed, any of the giblets. They all go into the stock pot, along with the neck and all the bones (which I remove before roasting, except for wings and drumsticks). All the meat off the bones, the simmered giblets, and the browned liver, are chopped up for the stuffing.
Turkey is too nummy to waste anything.
I used to put them into the gravy, but that’s too lumpy.
