Due to the use of calvados and honeyed Scotch herbal liqueur, for a brief moment of madness, this riff on a Rusty Nail was going to be called 'French Nail...
Coming back after using this drink to help finish off a bottle of Berneroy Fine Calvados: making this with the Berneroy, Johnnie Walker Black, & Drambuie resulted in a great equal-parts drink, with relatively easy to find ingredients, if you're in the mood for a drink with a decent amount of "smoke". I'd maybe rate it more like a 4 on the sweet/dry/sour scale, but it still felt well-balanced by smoke/herbal/bitter components.
