Tequila Old Fashioned with Aperitivo Bitters

Chill a rocks glass by filling it with ice water and letting it sit for 2 minutes, then discard the water and set the glass aside.

If you wish to salt the rim, spread a small pinch of salt on a small plate. Cut a thin strip from the lime, run it lightly around the outer rim of the glass, then press the rim briefly into the salt to coat evenly.

Add the agave syrup directly into the chilled rocks glass using a jigger with etched lines to measure precisely.

Add the aperitivo bitters on top of the agave, holding the bottle at a slight angle and giving it 4 measured dashes.

Pour the blanco tequila into the glass, measured carefully to ensure balance.

Cut a round slice from the orange, then express the peel over the glass by bending it so the inner skin faces the drink, releasing the aromatic oils into the air above the glass. Run the expressed peel around the rim once, then place it into the glass as a garnish.

Fill a large mixing vessel with a single large ice cube or sphere and transfer the cocktail from the rocks glass into it. Stir steadily for 25-30 seconds, until the drink is thoroughly chilled and properly diluted.

Return the stirred cocktail to the original rocks glass, placing the orange peel garnish so it rests against the side of the glass. Optionally top with club soda poured slowly down the side of the glass for a gentle lift.

Serve immediately, savoring the ceremony of each sip. The drink is ready when the glass is cool to the touch and the aromas rise freely from the rim.
