I can imagine Winnie sipping one of these accompanied by a fat cigar. This Churchillian is as formidable as its namesake and you may prefer it tamed with...
When a mixologist makes quite a claim for one of his creations, for example by naming it after a towering statesman, we think it entirely reasonable to conjecture that it was just such a drink that prompted Mr Churchill's said aversion to cocktails. Which, in an oddly satisfactory way, makes the naming of this cocktail perfect.
As suggested, served on the rocks, and well stirred down. Intense flavours, but balanced, none predominating over the others. I like how the various liqueurs’ flavours progressively emerge, like a good scotch. Recommended.
Over a year since your comment, but just wanted to say I agree wholeheartedly. At first taste I thought I should have done an absinthe rinse then dumped, but it faded to the background as the drink went on. Only critique is the chartreuse didn't quite show up, may use faccia brutto next time and save the chartreuse for all the Last Word variations. I did use a large ice sphere, so that did contribute to the evolution (positive) as dilution increased.
