Cranberry Panna Cotta

This seemed like such a good idea - panna cotta without heavy cream (just butter milk) and cranberries for fruit. As written, there isn't enough sugar for the cranberries, especially with the buttermilk. So much tartness, even my sour-loving son didn't think it worked. I nearly doubled the sugar, and also added some salt. I think the recipe would be better with a sweeter fruit. And some heavy cream. Or skip the fruit, and use lemon zest.

Update: As I ate the leftovers for breakfast, I realized that there were few redeeming features of these "desserts", and in fact nobody liked them. So I downgraded the rating to 2.
