By now you’ve probably been there: A perfect-looking melon in your shopping basket turn out to be watery and bland. Or maybe you waited too long to pick one from your back yard, then watched as it become mushy before you could cut into it.
Here’s the thing: Melons aren’t failing you; they’re deceiving you. All that flesh is hidden beneath layers of rind, and the clues about when to harvest seem to come and go at random. Once you learn how to read them, however, everything change: Guessing becomes an exercise in confidence, and you’ll know exactly when to expect deliciousness.
How to Pick a Ripe Melon
As seen in chart above, there’s rarely only one factor involved in ripeness. It’s a pile of evidence. A collective of the physical characteristics of the fruit; you’re seeking a consensus.
And the most well-known of these indicators is what I call the slip stage, particularly in fruits such as cantaloupes (a.k.a. Muskmelons). A full slip happens if you give stem a gentle tug and it comes away cleanly from the fruit, which signals that the plant is ready to go. Still locked tight? Then the fruit is still taking in nutrients. Already dropping off on her own? It may be too late. It can be a matter of milliseconds. You want that sweet spot between the two, where the connection releases but the flesh remain firm. Ahh…
With other types, though, don’t rely on them just slipping. Some don’t slip at all (such as watermelons). What then? Watermelons hang on, until, well, overripe. Look to the ground spot instead. The color of a watermelon’s rind isn’t always an indicator. The creamy yellow part where it sat on the ground will tell you more. White means it’s still cooking, but buttery yellow is best.
See the infographic: It makes clear that main indicator varies by variety of melon. Match your fruit to the test. A slip test applied to a watermelon won’t tell you anything useful, since the measure don’t pertain to watermelons.
The final verdict is something you won’t be able to judge while out in the field: it has to be sweet. How do we know? Brix, baby. The term refers to sugar content, which most market melon simply aren’t at when picked (they’ve got to hold up to all that shipping). Sure, they’re still firm, but not at all like a vine-ripe melon; that complexity just isn’t there yet. Home gardeners has the luxury of waiting for that last burst of sweetness. And apparently some of the best varieties… Including Canary or Charentais, can actualy hit much higher levels of sweetness than average commercially available ones. So why does your homemade melon seem to taste so much better different than what came from the supermarket? Because it got to finish doing what it was sent here to do.
The other biological division with storage implications: Are your melons climacteric, which means that once picked, they’ll keep getting softer and even more ripe? If so, give them a few days at room temperature to really open up their aromas. Or are they non-climacteric (such as those old-fashioned watermelons)? No; once they are off the vine, they will not get any sweeter. The sugar was set the moment the stem was cut. Catch them at their prime on the plant. Fridge-early wouldn’t of harm a non-climacteric melon, and leaving one out on the counter won’t improve it, either. Just age.
But let’s not overthink this; follow your nose. A ripe melon smells perfumey and sweet at its blossom end. Why? It attracts pollinators (the fruit’s perfume is its signal of prime-time flavor). And that’s also what you should follow. Trust me, it’s a good sign. Add in an appropriate spot or slip color, a dull rind, and the proper heaviness, and voila: a recipe for success.
Forget following the calendar. The plant will tell you when the time has come. Learn the signs, heed the biology (and you’ll never again eat a blah melon). It’s simple science.
