Though the fruits are starting to roll in at nation-wide farmer's markets, it's still early enough in many places that an unripe peach or too-tart apple might make its way into the mix.
If you find yourself with such a fruit, don't throw it away: cook it! Here's how...
While cooking doesn't magically cause unripe fruit to ripen, it does do three things:
1. It enhances sweet and sour flavors in the fruit.
2. It decreases bitterness and astringency (that "fuzzy" flavor).
3. It softens the fruit and makes it edible.
Our favorite way to cook these fruits is by poaching. This simply means covering your fruit with liquid and simmering until the fruit is soft.
Stone fruits and those with a core of seeds are the best for poaching. Pears, peaches, apples, and even plums do well.
Any liquid--even water--can be used as a poaching liquid. For extra flavor, we like to use wine, beer, or a simple syrup (pre-made). You can also infuse the poaching liquid with other spices before adding the fruit. Cinnamon sticks, cloves, and ginger all make particularly good mulling spices.
How To Poach Fruit
Cut the fruit in half and remove the stone or core. If desired, peel your fruit before cutting it. (The skin on apples and peaches will also loosen during cooking and can be discarded later.)
In a sauce pan big enough to hold your fruit, bring your poaching liquid to a boil, adding any extra spices. Use enough poaching liquid to cover your fruit.
Reduce the liquid to a simmer and add your fruit. Poach until the fruit is soft and can be easily poked with a skewer. Cooking time will be any where from 10 minutes to 45 minutes, depending on how ripe your fruit was to begin with.
This fruit can be eaten right away or you can refrigerate it in the poaching liquid overnight. The fruit will continue to absorb the flavors of the poaching liquid, and the flavors will be more intense the longer it sits.

Why would you "throw away" an unripe peach or nectarine??? The paper bag method works wonderfully. I just had a ripe, juicy nectarine with lunch that was hard as a rock when I bought it.
My favourite thing to do with unripe fruit (especially pears, which seem to be perfectly ripe for about 6 hours - on their way from rock-hard to mushy) is to roast it using the following method (recipe thanks to Martha Stewart's Everyday Food magazine):
Roasted Pears and Dried Fruit
2/3 cup apple cider
3 tablespoons light-brown sugar
2 tablespoons unsalted butter, melted
3 firm Bartlett pears, cored and cut into 8 wedges each
3/4 cup dried cherries
3/4 cup pitted prunes
Zest of 1 lemon, removed in wide strips with a vegetable peeler
1/2 lemon, juiced
1/3 cup reduced-fat sour cream
Directions
1. Preheat oven to 400 degrees. In a 9-by-13-inch baking dish, whisk together apple cider, 2 tablespoons sugar, and butter. Add pears, dried cherries, prunes, and lemon zest and juice; toss to combine.
2. Cover with aluminum foil, and bake 15 minutes; remove foil and continue to bake, tossing once, until fruit is tender and beginning to brown, 20 to 25 minutes more.
3. In a small bowl, whisk together sour cream and remaining tablespoon sugar. Serve warm, or at room temperature, with sweetened sour cream.
(It's also fabulous over ice cream, or on your morning oatmeal!)
