Vegetarian Watercress Red Dates Longan Soup

Watercress (Nasturtium officinale) grows well in water and are widely cultivated throughout Asia. Old water cress plant that have produced flowers are bitter, so it is wise to choose young plants for your cooking. Watercress is rich in iodine, iron, calcium, folic acid, Vitamin C and A. Apart from that watercress is known to prevent lung cancer, aid digestion and prevent thyroid problem.
I normally use watercress to cook soup. I have added some Chinese Red dates (ang cho) which is good in improving Chi. For some additional sweetness, I also put in some dried longan which is effective in warming up our body! Check out this clear watercress soup with longan and Chinese red dates (ang cho) recipe.
