This is gonna hurt somebody's feelings, but....
I think creme bouquet is absolutely nasty & disgusting. The one time I had icing that was made with it and I was told what it was, was when I realized that THAT was the flavor I've tasted in every grocery store cake I've ever had in my life. I would hardly call it gourmet
ETA: I posted in response to OP's original Q, w/o reading the rest of the thread. I have never had wedding bouquet. HAGD!
