Want to even the temp between thighs and breasts
A couple tips -- make sure the legs are toward the back of the oven, where it's hotter. And if worse comes to worse (if the breast is done well before the legs), you can cut the legs/thighs off and throw them back in the oven to finish cooking, and just tent the breast with foil to keep it warm.
I agree, cut off the legs and put them back in
This may sound strange but it is the way I always do my turkey so I don't have overdone breasts and underdone dark meat.Take the turkey out when the breast reaches 160degrees. Cut off the legs an thighs an put them in a roaster with a little braising liquid an return to the oven to continue to cook for another hous. The breast meat can be covered with foil until the dark meat is ready. The mwhite meat will continue to cook some from the residual heat.
