Fruitcake.
Not the ready-made type from the store (horrid), but a proper one, made at home, aged for a month with a couple of shots of rum or whiskey added during aging, and topped off once a week or so.
I have a good recipe from my mom, but don't make it because in our house, I would be the only one eating it. One son hates fruit, Mrs. Subversive can't have the sugar, older son might eat some when visiting but mostly it would be me (too many calories).
