    Watermelon rum drink

    To celebrate my blogiversary I share with you a summer alcoholic cocktail drink - watermelon rum sour with thyme aroma. This cocktail can be served in any summer gathering, picnic or even dinner. Another great cocktail for summer is my green gin, be sure to check it out as well!

    The star of this cocktail is the juicy and succulent watermelon, which brings a burst of natural sweetness to the mix. Paired with the bright acidity of fresh lemon juice and a touch of thyme simple syrup to balance the flavors, the result is a harmonious blend that tantalizes the senses.

    To take this cocktail to the next level, we add a generous splash of white rum, infusing the drink with a hint of Caribbean spirit. The rum's subtle complexity complements the watermelon's sweetness, creating a well-rounded and satisfying sip.

    How to make simple syrup

    In order to get thyme aroma, we need to create a sugar syrup and infuse thyme in it. To make sugar syrup you need an equal amount of sugar and water (½ cup of each) and you cook it on high until all the sugar is dissolved. Than you place a few sprigs of fresh thyme in the syrup and let it sit for 1-2 hours. Finally, you sift the syrup and it will be ready to use in any drink. You can make it ahead of time and save it in the fridge for when you mix the drink. If you want a different aroma, you can replace the thyme with other herbs you like, like basil for instance.

    In addition, if you want you can change the watermelon to another fruit like red grapefruit or orange or grapes, just make sure you use fruits without seeds!

    Tips to enhance your watermelon rum sour cocktail experience:

    Choose Ripe Watermelon

    Opt for fully ripe watermelon for the best flavor and sweetness. Look for a watermelon with a deep, uniform color, and a hollow sound when tapped.

    Muddle with Care

    When muddling the watermelon slices, be gentle to extract the juice without pulverizing the seeds or creating excessive pulp. A wooden muddler or a spoon can be used for this purpose.

    Use Quality Rum

    Select a high-quality rum that complements the fruity flavors of the watermelon. Light or white rum is generally preferred for its clean and versatile profile.

    Experiment with Thyme Syrup

    The sugar thyme syrup adds a unique twist to the cocktail. Feel free to adjust the amount of syrup based on your desired level of sweetness. You can also infuse the syrup with additional herbs or spices for added complexity.

    Freshly Squeezed Lemon Juice

    For the perfect balance of acidity, use freshly squeezed lemon juice rather than bottled juice. It adds a bright and vibrant tang to the cocktail.

    Chill Ingredients

    Make sure all your ingredients, including the rum, lemon juice, and watermelon puree, are chilled before mixing. This helps to create a refreshing and well-blended cocktail.

    Garnish Creatively

    Get creative with your garnishes. Aside from watermelon slices and fresh thyme branches, you can also add a citrus twist with a lemon or lime wheel. Edible flowers or mint leaves can provide an elegant touch.

    Adjust Sweetness and Acidity

    Taste your cocktail before serving and adjust the sweetness or acidity as desired. You can add more simple syrup if it's too tart, or squeeze in a bit more lemon juice if it's too sweet.

    Serve Fresh and Cold

    Watermelon cocktails are best enjoyed fresh and cold. Serve them immediately after preparing to maintain their vibrant flavors and ensure a refreshing drinking experience.

    Experiment and Personalize

    Don't be afraid to experiment and personalize the recipe to suit your preferences. You can try different variations by adding a splash of another fruit juice, incorporating a flavored rum, or even introducing a hint of spice with a dash of cayenne pepper or ginger.

    Remember, the key to a great watermelon rum sour cocktail is the balance of flavors, so feel free to adjust the ingredients according to your taste. Enjoy sipping on this tropical delight and let the refreshing flavors transport you to a blissful oasis. Cheers!
