I've never tired the DW turkey legs but the reviews from the you-tube make me want to tray to make them.
Here's the link to the video.
I got two hints from the video.
One, they inject a salt water cure into the legs muscle tissue. They may use just water and Morton Tender Quick. http://www.mortonsalt.com/products/meatcuring/tenderquick.html
If the turkey legs are sweet they may use Morton Sugar Cure Plain http://www.mortonsalt.com/products/meatcuring/sugarcure.html
They may inject the brine through the top exposed muscle so there's not a bunch of holes in the skin.
Two, they slow cook in a smoker for six hours. They have the finished product in a hold over oven. The skin appears light. My guess of wood may be apple.
Has anyone who has tasted one of these legs able to say what kind of wood they used?
