I am in fact the person in charge of preparing the holiday meal, and have in the past. For a special meal, if you find it too difficult to make a traditional dish, perhaps you should either invite family members over to help, or host a different meal.
We have a traditional food on Christmas Eve and over the years other foods have been added because not everyone likes the traditional food. That's fine. But if you say you're hosting Christmas Eve and aren't providing that food, I'd definitely be disappointed. I still would go, because getting together with family is more important, but the disappointment would be something I'd have to deal with.
