    Ingredients needed for watermelon martinis
    Ingredient quantities can be found in the recipe card at the bottom of this post.
    • Watermelon Syrup - The star of the show!!! Our watermelon cocktail recipes are made with a quick, 5 Minute Watermelon Simple Syrup. All you need is some seedless watermelon and a bit of sugar! The recipe is included below but be sure to check out the full post for tips on picking a perfect watermelon and more watermelon drink ideas!
    • Vodka or Gin - Use your favorite bottle of vodka for martinis that are bursting with the natural sweetness and flavors of fresh watermelon juice.
      • You can also experiment with infused vodka. For gin martinis, we recommend using a Spring or Summer style gin that is lighter and won't overpower the delicious Summer fruit!
    • Triple Sec, Cointreau or Grand Marnier - A little orange liqueur pairs perfectly. For a lower alcohol content, substitute more watermelon or orange juice.
    • Lemon Juice - A touch of bright citrus juice helps to balance the fresh flavors with a touch of tartness.
    • Ice - For shaking!
