In a cast iron pot, large enough to fit your bird in, heat up a little
cooking oil and a nob of salted
butter.
Place your
turkey on its side, then add the trimmings (neck, and wings chopped up) around it, cover and put it in the oven for 20mins. When 20mins have past turn your
turkey on the other side and cook it for another 20 mins. Finally, put it on its back and cook it for another 20 minutes but without the lid.
