How to Pick the Perfect Watermelon

The knock test: Knock with your knuckles.

• Hollow sound = ripe, juicy, ready


• Dull thud = underripe or overripe

The field spot: Flip it over. Look for the yellow patch.

• Creamy yellow = sun-ripened, sweet


• White or pale = picked too early

The weight test: Heavier = more water = juicier.
The shape: Round ones tend to be sweeter.
