Start by assembling all your ingredients.

Fill your glass with ice and set it aside to chill.

Using a jigger, measure out 1 ounce each of dry gin, dry vermouth, and bitter liqueur.

In a mixing glass, add the measured spirits and fill it with ice.

Using a bar spoon, stir the mixture for about 30 seconds.

Remove the ice from your chilled glass and strain the cocktail mixture into it.

Twist an orange peel over the drink to release its oils, then drop it in as a garnish.

Take a moment to admire your creation before taking that first sip.
