Firefly Cocktail Recipe

A simple drink to make that may quickly become a favorite, the firefly mixes vodka and grapefruit in the popular greyhound cocktail with sweet syrup that is grenadine. This drink has two functions: One is to flavor the vodka, and two is to add sugar. It balances out the tartness of the grapefruit and gives it a beautiful glow with the gradual effects of a tequila sunrise. This drink’s equally delightful for brunch as it is for an afternoon on the patio or late evening with the fireflies. 

Recipe Variations

The drink does not require a garnish, but adding a slice of citrus fruit will make it more visually appealing. The best fruit to use is grapefruit, but lemon or lime slices will do just as well. A pitcher of this drink is the perfect way to enjoy it. Make sure you adjust the amount of vodka and grapefruit juice to the number of servings you need and mix it all together. You may want to experiment with different kinds of vodkas in the firefly. Service will be in tall glasses with ice, and you can top the drink with grenadine upon serving. While citrus vodka seems logical, you may want to try something that adds a bit more contrast, such as strawberry, raspberry, or pineapple. The combination of grapefruit and spice offers a superb flavor balance, so try this drink with a homemade hot pepper-infused vodka. Infusions typically take hours, not days, so take care to balance the pepper and do not forget to allow time for the process. 


If you’re going to make a citrus cocktail, it will taste best with freshly squeezed juice. If you want to enjoy the most juice from a grapefruit, warm it up to room temperature. Let it suffer a little more as you press it against the counter. Now cut it into pieces and press it with a manual juicer or reamer. A grapefruit will yield about 3/4 cup (about 5 to 6 ounces) of juice, and it’s easy to make homemade grenadine in a few different ways. A bottle of pomegranate juice can be purchased easily, or you can use fresh pomegranates. Unlike commercial products, homemade grenadine lacks the preservatives necessary for longer shelf life, so that it will only last about three weeks. Even though you do not have to use your best vodka for the firefly. You should steer clear of the cheapest vodka and instead choose a smooth middle ground one.
