1 fluid ounce cranberry juice
1 fluid ounce vanilla flavored vodka
1/2 fluid ounce grenadine syrup
Pour the cranberry juice, vodka, and grenadine into a cocktail shaker over ice. Cover, and shake until the outside of the shaker has frosted. Strain into a chilled martini glass, and garnish with a strawberry on the rim of the glass to serve.
