Basil Lime Cooler Recipe

For the Basil Syrup: Combine water, sugar, and basil leaves in a small saucepan. Heat over high heat until boiling, stirring to dissolve sugar. Reduce to a simmer and continue to cook for 10 minutes. Remove from heat and let cool. Strain through a fine mesh strainer. Basil syrup will keep for one week in a sealed container in the refrigerator. For the Cocktail: Combine 1 ounce basil syrup, lime juice, and vodka in a cocktail shaker filled with ice. Shake vigorously for 10 seconds. Fill a collins glass with ice, then strain the cocktail into the glass. Add extra basil leaves to the glass, top with seltzer and stir gently. Garnish with straw and basil sprig.
