The Ultimate Cosmopolitan

Chill a martini glass by placing it in the freezer for at least 15 minutes or filling it with ice water.

In a cocktail shaker, combine 1.5 oz of premium citrus vodka (such as Grey Goose), 1 oz of Cointreau, 0.75 oz of fresh lime juice, and 0.25 oz of cranberry juice cocktail.

Add ice to the shaker until it's about two-thirds full. Seal the shaker tightly.

Shake vigorously for 15-20 seconds until the shaker is well-chilled.

Strain the cocktail into the chilled martini glass, ensuring no ice chips enter the glass.

Garnish with a flamed orange zest. Express the oils over the drink by squeezing the peel and then dropping it into the glass.
