In a cocktail shaker, pour in 4 ounces of cranberry juice, 2 ounces of vodka, 1 ounce of elderflower liqueur, and the juice of half a fresh lemon. Add 1 teaspoon of granulated sugar and stir gently to combine the ingredients.

Fill the cocktail shaker with a generous amount of ice (approximately 1 cup), seal it tightly, and shake vigorously for about 15-20 seconds until the outside of the shaker feels cold and frosty.

Grab a chilled martini glass and carefully strain the mixture into it using a fine mesh strainer to ensure a smooth pour without any ice shards.

For the finishing touch, skewer a few fresh cranberries and a couple of mint leaves, placing them either directly into the glass or floating them on top for an eye-catching presentation.
