What causes a tomato to have a bumpy blossom?
What it looks like: Catfacing makes tomatoes appear deformed. The blossom end is rippled, bumpy and lumpy.#N#What causes it: Plants pollinated during cool evenings, when the temperatures hover around 50 to 55 degrees F, are subject to catfacing. Blossoms fall off when temperatures drop too low. However, if the flower is pollinating before the petals begin to drop off, some stick to the developing tomato. This creates the lumps and bumps typical of catfacing.#N#What to do about it: If possible, plant tomatoes a little later in the season. Make sure the weather has truly warmed up enough to support proper tomato development. Devices such as a “Wall of Water”—a circle of water-filled plastic tubes—raise temperatures near the tomato and help keep them high enough on cold nights to prevent cold-related problems. Using black-plastic spread on the soil can also help. As the plastic heats during the day, it releases the heat back towards the plants at night. Black plastic can be used as a temporary measure until the temperatures warm up enough that it’s no longer needed. Catfaced tomatoes are safe to eat; simply cut away the scarred areas.

You can use the oven to slowly bake tomatoes until they collapse, and serve or freeze them as delicious "half-dried" tomatoes, but the oven cannot handle the second half of dehydrating tomatoes, in which they change from soft goo to richly colored leathery pieces. For this, you need a proper electric or solar dehydrator, which bathes tomatoes in a gentle wind of warm, dry air.
Can you dry cherry tomatoes?
All types of tomatoes can be dried, and I think drying is the best way to preserve juicy cherry tomatoes and large slicing tomatoes that never found their way to a sandwich.
