1 oz Espresso (chilled)
1 oz Fernet Branca
1⁄2 oz Mezcal, Del Maguey Vida
1⁄2 oz Walnut Liqueur, Nocello
1⁄4 oz Agave syrup
1⁄4 oz Bitters (Bittermilk #6 Oaxacan Old Fashioned)
1 ds Peychaud's Bitters
1 twst Orange peel
Instructions
Shake dry then with ice. Express peel and use as garnish or discard.
Notes
Don't know what a suitable substitute for the Bittermilk would be, but I don't think Bittermens would be it.
Have also garnished with a couple cardamom pods, or even a bit of alder smoked sea salt atop the foam. Go nuts.
