At Thanksgiving, my family has a completely traditional New England dinner with assorted pies. At Christmas, we have an open house with a buffet consisting of whatever anyone wants on it. I am obligated to produce any dessert requested (in advance) by any family member. So far, I've been asked for Pumpkin Chiffon Pie, Orange Rice Pudding, and Bailey's Irish Cream/White Chocolate Cheesecake, with more requests to come. My personal favorite is Frangelico/dark chocolate mousse. (No traditional fruit pies in this bunch!)
I also do all the appetizers and breads/rolls.
I love cooking for Christmas!
