I've only used it in icing. The kind I've tried, so far, is CK Brand. I thought (mistakenly) that it was the same as Wedding Bouquet, so when I made Sharon Zambito's HRS BC and used 4 T of the flavoring, my BC tasted just like a dreamsicle! So I ended up coloring it orange and topped vanilla cupcakes with it.
Now, I use it sparingly, unless I'm going for a dreamsicle taste. Depending on the size of the batch of BC I'm making, I'll use about 1/4 of the total flavoring as Cream Bouquet.
