To make this easy How to Make a Watermelon Keg You’ll need the following ingredients:
1 Watermelon (medium to large)
½ – 1 Cup Vodka (can substitute gin, tequila, or other clear spirit)
Granulated Sugar (Optional), to taste (start with 1 tablespoon of sugar and adjust to your taste)
5-10 Leaves Fresh Mint (can substitute basil, or other fresh herbs)
Fruit corer (or sharp knife)
Watermelon keg tapping kit (or replacement beverage dispenser spigot)
Cut a thin slice of rind off of the flatter end of the watermelon to create a flat, stable base. Be careful to only slice off the rind and not expose any of the watermelon flesh (this will help prevent leaks). Or, if you have a large stable bowl that can hold the watermelon upright, you can skip this step and leave the watermelon intact.
Slice off the opposite end about ¼ of the way down the watermelon to expose the fruit. (Save this piece; it will later serve as the lid.) Scoop out the inside of the watermelon with an ice cream scoop or other large spoon, and set the flesh aside.
Use a corer to create a small opening, about ¼ of the way up from the bottom end of the watermelon, and attach a keg tapping kit to the watermelon shell. Set the watermelon keg aside.
Using a blender, puree the watermelon flesh with the vodka, mint, and sugar until it’s completely liquid. If needed, strain the watermelon mixture to remove the seeds. Pour the mixture back into the watermelon and place the lid back on. If desired, use toothpicks or skewers to secure the lid to the watermelon.
The quantities used in this recipe are for a medium-sized watermelon. Start with ½ cup of vodka when blending, taste, and add more if desired. If the watermelon is naturally sweet, you may not need additional sugar.
For faster, smoother pouring, leave the lid slightly ajar or use the corer to cut a vent hole in the lid.
