I make a variation of this drink for my Halloween menu appropriately named "the Ghost of Smokey Joe." Same measurements but swap the gin for Rye and add a layer of Islay scotch over the top for a little smoke.

Your modifications are genius. Made tonight with Michter’s Rye and Ardneg 10. Surely going into the winter rotation.

Simply delightful. I used Monkey Shoulder and am looking forward to the nuances afforded with the use of different blended Scotch.
