How to Pick a Watermelon
Start by looking at the skin's "finish." A ripe watermelon will have a dull skin—which is somewhat unexpected. You also don't want to see bruises, spots, or cracks. You'll also notice most watermelons develop a spot where they rest on the ground, and when it's yellow (and you don't see any stripes on the patch), the melon should be ripe and ready to slice. After all that, you can tap or thump the melon with your palm—a ripe watermelon should sound hollow and make a thunk sound. Then learn what fruits and vegetables are in season every month of the year.
How to Pick a Cantaloupe or Honeydew
To choose a cantaloupe or honeydew, start by checking the number of segments or dark furrows. The more the better! Then, give the melon a sniff where it was attached to the vine. It should have a subtle, sweet smell but not a strong one (that's a sign of an over-ripe fruit). Be sure to check the melon's color and tone. The best and sweetest cantaloupe should have golden undertones. Like the watermelon, a dull honeydew is a ripe honeydew.
