This sweet little orange is the fruit of the mandarin tree. It is packed full of vitamin C, fibre and antioxidants. Its flesh is among the least acidic in the citrus family, thus making it easier to digest than oranges and grapefruit, for instance.This guilt-free treat is low in calories—sweet tooth foodies rejoice! Mandarins are just as delicious on their own as for garnish on cocktails, salads and desserts
