This is the ultimate Thanksgiving/Christmas dinner leftover recipe. The recipe keeps in mind that the ingredients being used are from separate dishes that are *already* seasoned. If you are making either of the potatoes from scratch for the recipe, go ahead and season them as if you were making that dish to serve as a side. The same with the gravy, if it is not homemade roasted turkey gravy, add some more seasoning to it. Of course you do not have to have leftovers to make this, but it is a good way to use up the turkey, mashed potatoes, sweet potatoes and gravy without the dish tasting like leftovers. I have also made it with chicken with excellent results. This is a real family pleaser and our 4 year old actually asks for this for dinner a lot. The original recipe was adapted from Chef Jimmy Bradley of the Red Cat in New York City. It can also be prepared in individual 1 1/2-cup ramekins; check them for doneness after 20 minutes. WINE: A bighearted Chardonnay will echo the texture of the smooth gravy and the soft mashed potato topping. Look for a reasonably priced, fruity wine, such as Australia’s 1999 Rosemount or the 1999 Lindemans Bin 65.
