Also, it's a big drink for a Coupe (at least, for ours). We went, somewhat reluctantly, with a Rocks Glass, chilled, no ice. Perhaps our good host might edit the "Glass" description to indicate an ideal volume.
Very tasty indeed. Having no Cream Sherry (we, obviously mistakenly, had always thought it to be a tipple for little old ladies), we improvised with a bit of PX and a bit of Fino...not sure if that's by the book. Our good host has lately been drawing our attention to some magic Sherry cocktails. We're loving it.
One doesn't really need to compromise the taste for the fun. We split the 'sweet' 15ml Blue Curacao and 10ml Triple Sec (or sometimes the other way around). It's still the pretty blue of your bonnie lass's eyes that are the light of the world.
