Watermelon juice or puree not only makes for a refreshing base when used in summer cocktails and spiked punches, the melon itself serves as a festive and distinct serving bowl. Using a watermelon as a punch bowl not only adds a fruity flavor to your beverage, it acts as an excellent conversation piece. Once you've prepared the bowl and get to the mixing, you'll use the same techniques you use to mix standard punches and cocktails.
Thoroughly wash a medium-large seedless watermelon by running it under cool water. Pat the melon dry and place it sideways on a cutting board.
Cut about 1/4 to 1/2 inch off the stem end of the watermelon, using a kitchen knife. This makes for a flat base, allowing you to stand the melon up like a bowl.
Keep the fruit on its side and cut the top third from the watermelon. Cut enough off so that you can easily access the inside of the melon and use it as a bowl.
Scoop out the fleshy fruit of the melon using a strong spoon or ice cream scoop. Transfer the fruit into a bowl and save it for use in the punch or another recipe. Scoop down to the rind, so the interior of the melon has a smooth surface and can accommodate plenty of liquid.
Stand the watermelon upright and place it on a large serving tray. This helps contain any leaks or moisture and makes for a pleasing presentation.
Pour your punch ingredients directly into the hollow watermelon bowl one by one, following the order in which the ingredients are listed in your cocktail recipe. With the addition of each ingredient, slowly stir the liquids together with a mixing spoon or other long spoon, such as the one you used to scoop out the melon. Mix gently, as though “massaging” the drink.
Add any garnishes to complete your punch, and store the watermelon bowl in the refrigerator before serving.
