Prepare the cocktail garnish by trimming a small slice of orange peel.
Thread the orange peel, a sage leaf, and cranberries onto a decorative toothpick. Set them aside.
Fill a cocktail shaker or small pitcher with ice.
Add the vodka, fresh orange juice, cranberry juice, and Cointreau.
Shake or stir for 15 seconds.
Pour the cocktail through a sieve (to hold back the ice) into a martini glass.
Put 1 leaf of fresh sage in the palm of one hand and slap it with the other to release the oils and the flavor.
Place the sage leaf in the cocktail.
Add the prepared garnish and serve.
