Fruit 'n Veg had a special on: 3 packs of tomatoes for R12. So I bought them and dried them. Normally I halve the tomatoes ( the small Roma ones), arrange them on baking trays, sprinkle over a salt/pepper/sugar/spices mixture and bake them at 100°C for a few hours. But yesterday the oven stopped working in the middle of my drying-out session. I figured out one of the fuses had blown ( a woman needs a man like a fish needs a bicycle, hey?!).
So now the tomatoes have been actually drying outside in the sun for two days and it worked pretty well.
When they are dried to your taste ( I like them to still be slightly "wet" and then I eat them like candy) you can fill them into some glass jars and top the jars up with olive oil until all the dried tomatoes are completely covered.
