Upped the Scotch and used maple syrup as per Jose Cruz's comment (but only 5ml instead of 10). A bit sweet, but better than the normal version I made before,
Made a riff on this tonight using A’bunadh, Antica Formula, Honey Syrup, dash each Peychaud and Angostura (Fee’s), adding 1/3oz Laphroaig CS and served up. It’s sublime.
Used Johnnie Walker Black & Dolin Rouge. This did not taste as expected, but I like it. Much less "smoke" than anticipated. A 30 second stir was plenty dilution (maybe too much and/or freezing the mixing glass might help?). Nice balance of the scotch/smoke/vermouth/sweet/spice from all ingredients. Smooth, easy sipper. Curious to try sub'ing maple syrup for the sugar syrup, as recommended by Jose Cruz.
