Just cook the turkey until you can put an oven mit on and press down on the breast and the bird carcase structure collapses...Then it is fully cooked..
Mix some flour and butter into a paste,called a rue and then drain off the turkey fat ...
About three table spoons flour/butter mix..
Take the bird out of the pan and onto a plate..With the pan drained of grease spoon the flour/butter mixture into the pan drippin's and massage around the bottom of the pan...Use the potato and carrot water off the veggies and pour into the turkey pan....
Mix and massage that mixture around in the turkey pan while bringing to a rolling boil...Add salt and pepper...
You'll have the best pan gravy going...
Enjoy/..
