Place a coupe or rocks glass in the freezer 15-30 minutes before making the cocktail. While the glass is chilling, fresh brew 2 shots of espresso and set it aside to come to room temperature. It should take about 3-5 minutes.
Next, clean the skin of a orange. Then, use a y-peeler or cheese peeler to create a roughly 1in x 3in (2.5cm x 7.6cm) long strip of orange peel. Clean up the edges, shaping the peel into a parallelogram with a knife. Then, create a slit down the center of the peel leaving roughly 1/2in (1.3cm) of clearance at the top and bottom. Set your garnish aside. (If you have mini clothespins the middle slit is unnecessary.)
Measure out the tequila and Licor43, pouring each one into the smaller side of the cocktail shaker as you go. Next, pour in the espresso shots and add a few dashes of molé bitters to that same side.
Take the chilled glass out of the freezer as well as a large piece of ice. Drop the ice into the other side of the shaker and pour the liquid ingredients over the ice, close the shaker, and shake for 30-45 seconds. Strain into the chilled coupe glass, sans ice, or over a second large ice cube in the rocks glass.
Express the prepared orange peel over the drink by holding the top and bottom of peel horizontally and facing out. Squeeze down to release the oils. Rub the outside of the peel against the rim of the glass. Twist the peel after it's expressed and slide it onto the rim of the glass using the slit in the center. (Or pin the expressed orange peel to the glass)
