The highly-effective pairing of scotch and apple brandy in that last drink got me thinking about other options. I'm pretty sure I've combined tequila and applejack before, so why not mezcal? In fact, why not all three?
3/4 oz scotch (Dalmore 12 Year this time)
3/4 oz Laird's Straight Apple Brandy
1/4 oz mezcal (Del Maguey Vida Mezcal Joven)
1/2 oz sweet vermouth (Cinzano again)
1 dash Regan's No. 6 Orange Bitters
1 drop orange blossom water
Stir briefly over ice and strain into an old-fashioned glass. I don't understand this "garnish".
I tried this originally as a scaffa-style unchilled drink, but the dilution (more than the chilling) really seems to help take the edge off. I might try this with a bit of chilled water rather than ice next time.
