At a casual picnic, eat it with your hands. Take small bites to avoid having juice run down your chin, Lininger says, and keep a napkin handy. At more formal affairs, use a fork’s tines to flick seeds away and push them to the side of your plate. Then, use the edge of the fork to cut bite-size watermelon pieces. No utensils? Don’t worry if you encounter seeds. “The general rule for removing unwanted food from your mouth is to have it leave the same way it entered,” Lininger says. So if you’re eating watermelon with your hands and get a seed, remove it from your mouth using your thumb and forefinger; then, place it on a napkin.
