Stick to the traditional for the main meal or you’ll have upset family. Appetizers can be outside the box.
Will do the traditional meal and make some experimental side dishes to see if people will like them, if not, no biggie.
This is true. In my experience, people EXPECT things, at Thanksgiving - it’s like the Comfort Food Holiday, and folks don’t really like change on this day.
Do everything you’ve always done, and add something new, if you want to.
