A few years ago, we tried Principe Borghese, an Italian drying tomato. We have been happy with it. They can be rehydrated in boiling hot water, then drained and seasoned with olive oil, salt and herbs. It is the red tomato in the photo. We also tried drying the orange cherry-type tomato, called Sunsugar. The Sunsugar is the sweetest of our tomatoes. These are delicious, kind of like a tomato raisin.
