Place a rocks glass in the freezer 15-30 minutes before making the cocktail.
When ready, clean the skin of an orange. Then, use a y-peeler or knife to create a roughly 1in x 2in (2.5cm x 5cm) long strip of orange peel. Clean up the edges with a knife and gently cut away any pith that may be attached to the underside of peel. Set your garnish aside.
Next measure and pour your ingredients into a large, ice-filled mixing glass. Stir with a bar spoon for 30-45 seconds, to chill the cocktail.
In a separate (now chilled) glass, add a single extra large ice cube and pour in the chilled cocktail liquid.
Express your 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 and slip it into the drink.
Sip and enjoy!
