Vodka-infused watermelon is a fun and refreshing treat for summer parties and gatherings. The combination of juicy watermelon and vodka creates a boozy and fruity snack that is perfect for hot days. To make this treat, cut a hole in the watermelon and pour vodka into it. Let the watermelon soak up the vodka for a few hours in the refrigerator. Once infused, slice the watermelon into wedges and serve them chilled. The result is a sweet and slightly boozy watermelon that will keep you cool and refreshed all summer long.
