Wash and clean the tomatoes and cut them into 1.5 cm thick slices. Distribute on 2-3 baking trays covered with baking paper. Wash the rosemary, shake dry and pluck the needles from the twigs. Sprinkle tomatoes with sugar and rosemary. Dry in a preheated oven (fan-assisted oven: 75 °C) for 4-6 hours with the oven door slightly open. Peel and halve the garlic.
The tomatoes are ready when they have visibly shrunk and the tomato juice has evaporated. Remove the tomatoes and let them cool down. Put the tomatoes and garlic into a glass that has been rinsed hot beforehand. Pour oil over them until the tomatoes are covered. Sprinkle thickly with salt. Leave to stand for about 2 weeks.
Preparation time 4-6 1/2 hours
