You can choose to add the extra cream or not. You can purée the soup as directed for a smooth soup, or just a few pulses for something more chunky and rustic. Experiment as well with herbs or added cheeses. Suggestions from readers include using coriander (cilantro) instead of parsley, or adding some shredded Gouda. Reduce heat. Cover and simmer 25 minutes or until vegetables are very tender. Season to taste with salt. Garnish with parsley, chives or dill.
