For a big bash, go for an oversize "picnic" melon; for recipes, choose a smaller "icebox" one, or pick up a half or quartered melon. You'll find watermelons that are red, pink, yellow, or orange inside. "Seedless" types' white seeds are small, soft, and edible.

In Season: Melons need heat to sweeten; summer and early fall is their prime.

What to Look For: Tap a ripe melon and you'll hear a hollow thump. Look for a striped green rind that's smooth, round, and unblemished. Wedges should have firm, bright flesh.

How to Store: Store whole melons in a cool spot. Cover wedges in plastic and refrigerate up to 4 days.
