If memory serves, the coconut milk tended to separate in the oven, or at least got a grey look to it, but the result was still good; I think I ended up using the mixer to make it into a mashed sweet potato dish.

I didn't re-bake it after adding the coconut milk: it was just puréed and served instantly, which seemed to work for everyone.

Happy Thanksgiving to you and yours!

Thank you! Likewise. It was.
