Tomates Confites (slow roasted tomatoes)

I read about Clotilde's blog (chocolate and zucchini) more than a year ago, and I soon visited it. I loved it from the first moment I logged in, not only because of the recipes but above all the stories that that precede them. This was the first recipe that I tried. I had just come back to Modena after visiting my father in Bosnia and brought a load of home grown tomatoes that needed to be dealt with quickly. I served them to my friends in occasion of the end-of-summer-holiday barbique we organized in our garden, and everybody got literally excited. They vanished in a sec. Tip: if you prepare a large quantity (which I advise, considering the cooking time), freeze them and use whenever you like.
