In summer, unused tomatoes tend to rot. I buy mostly heirloom tomatoes, and even when kept out in the open, treated tenderly (just short of being coddled in cotton batting), a few will over-ripen and split and ugh, the smell is usually my first warning that the bottom tomato has given up.
In winter, in our house, unused grape tomatoes tend to dry out. Weird. Kept in their plastic pint container, in cool temperatures and fairly low humidity, they slowly turn wrinkly and slightly leathery. When I notice this happening, I usually slice them in half and add them to a stir-fry or saute -- nice juicy little nuggets of faux summer in my otherwise (mostly) seasonal dishes.
I had an entire pint go wrinkly not long ago, as I simply forgot about them. It happens. The wrinkly tomatoes were still juicy inside. I was in an experimenting mood, so I sliced the lot, put them in a baking dish, sluiced them with olive oil and a bit of salt, and roasted them. I was baking a pie that day, anyway.
I think the oven was set to 350F or 375F. I stirred the tomatoes every fifteen minutes so they wouldn't stick. Forty-five minutes later, I had a baking dish full of what tasted very like sun-dried tomatoes, but much squishier. Sweet, savory, chewy, with charred notes that were beyond delicious.
A few days later, these little flavor bombs became a homemade pizza topping, Mushrooms, anchovies, lots of shredded mozzarella, and fresh-made dough from my local gourmet shop, and behold. A thing of wonky well-meaning and very tasty beauty.
BTW sliced chorizo -- another wonderful product of the same gourmet shop -- is another revelation when roasted. The next time I made pizza it was chorizo, roasted tomatoes and "Mexican cheese mix" from Trader Joe's. There was space around the edges of the foil-lined baking sheet (yeah, no pizza stone in this house) so I laid out six spare slices to cook. SPICY BACON BEST EVER THING OMG.
Seriously, do the tomatoes thing and also the chorizo thing. Totally worth the trouble.
