another option would be to follow ed's instructions up until the point where suggests putting the squab in the oven. continue sauteing over low heat until the skin is very crispy. remove from the heat, flip the bird over in the pan and let it sit. the residual heat from the pan will continue to cook the flesh very slowly. this will give an even temperature all the way through the breast. i'm not going to give a specific cooking time, but rather suggest using your finger to test for doneness. if when you go to eat it, you find it cooked too much, do it less next time. trial and error has been the best instructor i've had. honestly, no more than 3 minutes after the flip. let the meat rest and slice it to have a look inside.
