If you are really going to plunge into the spirit of a watermelon festival, especially a watermelon festival in the Old South, you need some basic skills--and some spirits. I'm here to help. Just buy a medium-sized seedless watermelon and the liquor of your choice, then follow these easy steps.
Step 1: Use a small knife to gently cut a round hole in a watermelon to create a "plug." Do not cut a square or triangular hole, as that may cause your watermelon to crack.
Step 2: Use a corkscrew to remove the plug of watermelon rind from your watermelon. Trim the pink watermelon attached to the plug and eat it. Yum! Now take a teaspoon and scoop a little of the flesh out of the hole you made to make some space for the booze. Two or three spoonfuls should do it. Yum!
Step 3: Next, take something long and skinny, like this skewer that I used, and poke it into the flesh of the watermelon a few times at different angles. Watermelon has naturally occurring airspaces and you are creating channels for the booze to flow freely through the melon. Do not poke the skewer all the way through the other side of the melon! That will make it leak.
Next, pour about one cup of your favorite booze into the watermelon. You may have to pour it a little bit at a time and let it settle in. One cup should be about as much as will soak in. Some people swear by vodka or rum, but I prefer bourbon. It may sound strange, but when the bourbon has a chance to work its way through the fruit, the flavor is amazing.
Step 4: Replace the plug of watermelon rind you set aside in the watermelon. With the "plug side" up, place the watermelon back in the refrigerator for at least a couple of hours to let the booze percolate through the flesh and to cool the melon.
Finally, slice the watermelon like you would any other and enjoy!
P.S. Do not serve this to underage people.
