Hi, psobrasil! Lucky you, with all those gorgeous, luscious tomatoes!!
Unfortunately, I haven't been able to find a recipe for drying tomatoes - every other veggie under the sun, of course, but no tomatoes.
However, necessity being the mother of invention (I have all of about 5 pounds of extra toms here), I'm going to try drying a few this weekend anyway. I'm going to just slice them and lay them on the trays in my little bitty cheapo food dryer and see what happens. I also am going to slice some and dry in the oven on the lowest setting - my oven will go down to about 150 degrees, so I'm hoping that the 150 degrees with the oven door opened a couple of inches will do the trick. I believe they are dry enough when they get leathery, then you have to let them cool and put them all into a big open container like a dishpan and stir them a couple times a day for 2 weeks and then heat them again just to 175 degrees and let them cool again. At which point they're ready to store. Or anyway that's what my book, "Putting Food By" says about other foods, so I assume the same holds for tomatoes.
I'll let you know how they turn out. Meanwhile, enjoy the seeds and juice dripping off your chin!!:D
