Tasting Notes
The Whiskey Watermelon Martini is a refreshing, summery twist on a spirit-forward classic. Whiskey brings smooth, rich warmth that contrasts beautifully with the juicy, slightly sweet flavor of fresh watermelon. Lime juice adds a citrusy zip, and simple syrup balances it all with a gentle sweetness. Served ice-cold in a martini glass and optionally garnished with watermelon or mint, it’s both bold and refreshing—perfect for warm evenings or creative cocktail hours.
Equipment and Glassware
To create this cocktail, start by preparing the watermelon juice using a blender to purée the fruit, then strain it through a fine mesh strainer for a smooth, pulp-free result. You’ll also need a cocktail shaker to mix the ingredients thoroughly, along with a jigger for precise measurements and a strainer to ensure a clean pour.
For the best presentation, serve the finished drink in a chilled martini glass, which adds a touch of sophistication. To place garnishes with care—whether it’s a small watermelon wedge, lime twist, or mint sprig—use garnish tweezers or a cocktail pick for a refined look.
