You did everything right at the market (previous list) but when you get home, that peach is a little too lush. Here are some remedies for overripe fruit (stone fruit & figs. Also berries. Only one = melon-applicable)
  1. (Universal first step)
    Cut away and discard any possible mold. That's the only real deal breaker here. Soft, very ripe or dark areas are fine.
  2. Make a smoothie.
  3. Make instant jam.
    Just mash. Drizzles of fresh lemon or lime juice, plus a little honey might be nice but might also be unnecessary. Spread on toast. Best jam!
  4. Cook into a sauce.
    Pit and coarsely chop, then cook the fruit in a saucepan over low heat until saucy. Possibly add splashes of water or fruit juice during cooking if dry. Use anywhere you might like a fruit sauce; don't overlook the charm of this on savory things (grilled meat, if so inclined - or roasted squash) as well as dessert or French toast or pancakes.
  5. Make a cobbler or a crisp.
    Umpteen recipes are floating around online. They're all similar and simple. You'll find one.
  6. Bake a pie.
    Ditto online recipes - or your own personal favorite from Grandma.
  7. Upside-down cake.
    Pit and chop, arrange in a generously buttered cake pan. Top w a favorite vanilla cake batter and bake. Invert when cool.
  8. Crepe or blintz filling.
    Same procedure as instant jam, above.
  9. Fold into your favorite bread pudding or rice pudding.
    Easy and delicious.
  10. Roast it.
    Spread put the fruit (in chunks) in lightly nonstick-sprayed ceramic baking pan and bake at 375F for about 30 - or until done to your liking. (Loosen & move around a few times during.) Enjoy as a snack or light dessert w favorite cheese.
  11. And for melons...
    If overripe in a fermented-tasting kind of way, consider blending into your own new cocktail invention and garnish w mint.
  12. Make Norwegian fruit soup!
    I don't have any recipes off the top of my head, but Google does 😳

  13. Put it in a blender with vodka or whiskey. Drink the result topped up with seltzer (or champagne!)

  14. Make a (boozy) compote, and then make a grilled cheese sando with it. Last summer I did this with peaches and Sauvignon blanc (recipe below), but you could also do with berries and a red. Or you could opt out of the booze altogether, and use the compote for normal things, like eating with yogurt and toast.

  15. Cut it up and serve over plain yogurt and granola.
    As long as it's not fermented, I'll just cut it up and use in my breakfast yogurt with granola.

  16. Make Popsicles!
    It's summer! Get some popsicle molds and start popsing (yes I just turned popsicle into a verb). Recipes abound on the Internet and in cookbooks...
