It's interesting to hear and compare the various foods that are served traditionally at Thanksgiving. Aside from the typical turkey (roasted or fried or both), mashed potatoes and gravy, we always serve homemade noodles. Many of us opt to use the noodles in lieu of gravy on our mashed potatoes, and what a delicious treat that is.
Our sweet potatoes will vary, some years we get a mashed variety and some years sliced and candied. Our cranberries too differ year to year, but we never use canned jellied cranberry, it is always a recipe with fresh cranberries. And it wouldn't be Thanksgiving dinner without homemade rolls; my mother's are the best!
When we lived in New England, carrot casserole was a Thanksgiving dish tradition. Sliced cooked carrots layered with Velveeta cheese and buttered Ritz cracker crumbs. Yum. I'm not a big carrot fan, but these are wonderful.
I'd love to hear more unusual but traditional foods so please feel free to add yours in the comments.
