Yet ripeness can be a much more relative concept than one might expect.
Harold McGee, in his landmark book, "On Food and Cooking: The Science and Lore of the Kitchen," wrote that ripening was "long considered to be an early stage in the fruit's general disintegration. But now it's clear that ripening is a last, intense phase of life. As it ripens, the fruit actively prepares itself for its end, organizing itself into a feast for our eye and palate."
Ripeness has, of course, always mattered, but today's emphasis on local and seasonal foods may be honing and articulating an appetite for it as an ideal.
You can experience ripeness in two ways this season with two new books, both called "Ripe": Nigel Slater's recipe-filled musing on fruit called "Ripe: A Cook in the Orchard" (Ten Speed: $40) and Cheryl Sternman Rule's rainbow-hued book "Ripe: A Fresh, Colorful Approach to Fruits and Vegetables" (Running Press $25).
Still, determining when to join in on McGee's proverbial ripeness feast has long been dictated by necessity and personal taste. Slater, for example, writes lyrically of "walking round the garden late on an autumn morning, pushing past the spiders' webs that festoon the pathways and plucking those last, wine-colored berries from their blackened canes is as good as life gets."
Fruits and vegetables do reach a peak stage in life. A vine-ripened red tomato is a perfect example. But that doesn't mean the produce is inedible before or after that point, says Willi Galloway, author of "Grow Cook Eat: A Food Lover's Guide to Vegetable Gardening" (Sasquatch, $29.95).
She focuses on the delicious possibilities found in eating produce at the various stages of its life. How one prepares the vegetable or fruit will depend on the age, she says, noting that young small arugula leaves will end up raw in salads while older, tougher leaves go into pasta sauces.
Gardeners like Martin, Slater and Galloway have a far easier time deciding when something is ripe for them. The rest of us must follow the dictates of supermarkets and, if we're lucky, farmers markets or roadside stands. Use your senses to judge quality and ripeness. Touch, smell, nibble if you can; don't go by looks alone.
"Just because it looks perfect doesn't mean it will taste perfect," Rule says, urging consumers to ask questions, especially at farmers markets.
"Speak up, ask them to pick for you," she suggests. "Being bold and unafraid is my biggest piece of advice at farmers markets. And that goes for the produce manager at the supermarket as well."
