Uppu Manga also spelled Uppumanga refers to whole  or slices of  tender raw green mangoes immersed in a salt solution and stored safely in a Bharani, a traditional earthenware pot or ceramic jar which can be used later for various purposes, such as for making Curries, Chutneys and Pickles. 

Moreover, Uppu Manga refers to salt-brined raw mangoes or raw mangoes in brine. In Kerala, India, Uppu Manga is made from slices of tender raw mangoes then preserved by immersing them in a salt solution. If the mangoes are well brined/ preserved they can last until a year. 

It is said that Uppu Manga eaten with  Kanthari Mulaku (bird’s eye chilies) and Kanji  is one of Malayali's  favorite comfort food.

My friend in Allepey, Kerala, eat them straight from the jar or eat them sometimes with Kanji (rice porridge/gruel). I tasted my first Uppu Manga during my first meal (lunch) in Allepey as a side dish.
