This refreshing cocktail starts with a fresh ginger simple syrup, which melds with vodka, lime, and watermelon juice to give you all the flavors of summer in a glass. Mixologist Gabriel Orta finishes with a dramatic garnish of watermelon and fresh mint.
Ginger simple syrup: Bring water to a rolling boil. Meanwhile, use the edge of a spoon to scrape the skin off the ginger. Cut into chunks and place into the boiling water. Bring back to a boil and continue boiling for 10 minutes. Add sugar and stir to dissolve; reduce heat to low and simmer uncovered, 10 minutes. Remove from heat and cool to room temperature, 30 minutes. Strain ginger and store in a lidded container; it will keep indefinitely in refrigerator. (Note: Orta makes an extra big batch in the video. You can adjust the amount of ginger simple syrup you make by using a 1:2:2 ratio of ginger to water to sugar.)
Ramsey Collins: In a cocktail shaker, add lime juice, ginger simple syrup, watermelon juice, and vodka. Pull and rip mint sprigs to release oils and add to the cocktail shaker. Fill shaker with ice cubes, cover, and shake, about 10 seconds.
Assembly: Line the interior of a tall cocktail glass with a very thin slice of watermelon. Fill glass with crushed ice and strain cocktail into it. Garnish with additional mint sprigs, insert straw, and serve.
