You might consider serving this to someone who has little affinity for sweet cocktails and another with none for dry in the same round. If someone handed this to me as their twist on a Vesper I might find Mr. Bond's drink to be lacking a bit of something thereafter.
For my Wife, pure girly petrol. When she's drinking this I will not mention chocolate cake or anything else chocolate. Had to be very careful with the amount of frangelico or it would be too much. I wonder how this would work if whipped up with hazelnut yoghurt or just normal greek yoghurt, as a dessert of course.
This is a perfect after dinner drink. All the falvours work together well. Only issue is that they do drink easily, so you have to remember to just sip. Went wonderfully with a piece of chocolate angel food cake.
