Heat the tomatoes to peel them easier. Boil the peeled tomatoes with the orange juice and some salt. After boiling for a while, add the water, tomato paste, sugar and some pepper. Boil for 10 minutes. Clean and cut the zucchini in cubes. Add them into the saucepan and boil until the zucchini are cooked. Lower the heat temperature and add the cream. Stir well and do not let the soup boil. Serve hot with some parsley leaves on top and some cayen pepper.
