I make a version of this & I do think that the goat just really works with beets. This is such a
magnificent creation, I do want to make this version as well. I think that boursin would result in a completely different outcome. Beets are sweet and are perfectly offset by the tang of goat cheese.
Here is the one that I do and it really REALLY wows dinner guests.
I can't do goat cheese either, but have found a mix of cream cheese and bleu or feta
is a good choice if you don't want the added herbs of boursin. but I really like boursin too, which could also be "milded down" by adding some cream cheese.
