Of course no one wants to change Grandma's peach cobbler recipe or Mom's famous gravy but Thanksgiving is a great time to try new recipes. Since you'll probably have a lot of family together, go ahead a few weeks in advance and pick the recipe(s) that you want to experiment with. This will give you time to test the recipe and see if you life it. If you don't, there are thousands of other recipes out there that you can research and try. Your family will appreciate your new challenges and enjoy the taste testing.
