Now, give it a gentle tap with your knuckles. Listen closely. A ripe watermelon makes a deep, hollow sound—like a drum saying, “I’m full of juice!”
A dull thud? That’s a watery, under-ripe melon. A high-pitched ping? Run away. That means it’s overripe and mealy inside.
Practice on a few melons at the store. You’ll feel like a percussionist, and people might stare. Let them. You’re on a mission for sweetness.
