I don't think we have a thread currently that addresses this topic: What do you eat because it is part of your holiday tradition, despite that you would never eat any other time of year?
Mine would be toast smeared with one of those processed port wine cheese balls. It makes me think of spending the night at my grandparents' house and that Grandma did not have any hangups about what constituted breakfast food.
I also sometimes get an urge to make cocktail hotdogs in BBQ sauce and grape jelly. My aunt always had this as an appetizer and served it in her Descoware beanpot; she gave me the beanpot for Christmas a few years ago (I keep my wooden spoons in it), but every once in a while I feel the need to dump out the spoons and fill it with cocktail franks. I never actually eat them, but I get a weird desire to cook and serve them to others.
