You are not alone. It seems that all of us have at least a few foods that we indulge in during the holiday season. My list is probably longer than most, and I'm OK with that.
In the first years of my life, I had a dairy allergy. Even having a teaspoon of milk would give me a three day ear infection. So I had my bowl of Cheerios with soy milk, and orange sherbet was the only option when the family stopped at an ice cream parlor.
