A favorite summer fruit which is on everyone's list of favorites is Mangoes. Raw Mangoes are green and very sour and can be transformed into this flavorful cool drink.  Popularly called as Keri nu Panho or simply Pano in Gujarat, is a refreshing summer drink made from raw mangoes sweetened with jaggery and flavored with cardamon and saffron. There are multiple ways of preparation of this favorite drink and each household has a favorite recipe. I have a few alternatives listed here and you can go ahead and experiment to suite your taste. The addition of jaggery gives instant energy and strength to one who has worked in intense summer heat or one who has come from a summer expedition. The richness of iron in jaggery help renew the energy in oneself.
