THE ERICSON COCKTAIL
The nuances that make up the recipe is typically left to the bartender, requiring only that it contain the two main ingredients, stirred, shaken, or served at room temperature, but never with a straw.
Ingredients:
2 oz. mezcal
½ oz. amaro
  dash of chocolate bitters  
lemon peel
Pour 2 oz. of mezcal with a ½ oz. of amaro (Averna) in a mixing glass with ice — add a dash of chocolate bitters (completely unnecessary) — give that an extended stir, softer than a manhattan but not quite as soft as a martini — strain into a chilled Nick & Nora glass — press the essential oils of a lemon peel into the glass then toss the peel in.
