My family's Thanksgiving menu is pretty conventional: turkey (lately a free-range turkey to placate the semi-vegetarian elder daughter--me), baked potatoes (both white and sweet), stuffing (well, technically, dressing, since it's not cooked in the bird), gravy, cranberry sauce (always whole berry, and always homemade), and a green vegetable. Sometimes we have just a salad, sometimes there's a hot veggie as well. In short, a lot of stuff to fit on one plate. My dad has experimented with different kinds of stuffing; his current favorite is brown rice with apples and chestnuts. My husband and I bring the cranberries and the pies (one apple and one pumpkin), and his lattice crust always draws oohs and ahhs.
When celebrating Christmas at my in-laws' house, the real must-have is the cookies, and since everyone has a favorite, there are about four kinds that *must* be made: Russian tea cakes, date bars, peanut butter kisses, and chocolate crunchies. Lately we've dropped the gingerbread boys, since no one was really that attached to them, and brought back plain sugar cookies, since the little ones get to have a ball decorating them with different colors of frosting and generally making a mess.
