I started thinking about this question and have decided that, at Christmas, I must be about 6 years old! My only constant Christmas comfort food is my mom's chocolate chip cookies! The other food that always makes me happy at Christmas is a traditional turkey dinner. It's what we always have on Christmas day.
We usually do a leg of lamb on Christmas Eve but, aside from that, everything else changes.
OH! *lightbulb goes on* Here's what a love. That potato casserole with sour cream, cheddar cheese and green onions. I think we discovered a few years ago that many FoRTers have some variation of this recipe. It so fattening that we only have it once a year, but it's one of those things that I look forward to during the holidays.
