Peel the Green Mango and dice them in small pieces. Leave the seed intact.
Now, heat oil in a pan and temper it with dried Red Chili and Mustard Seeds
Now, add the diced Green Mango pieces along with the seed and turmeric powder. Stir it over low heat for a minute or so.
Now, add the water when the mango pieces start becoming soft.
Season with salt and add sugar.
Note: Adjust the amount of sugar as per the tanginess of the Green Mango.
Allow it to simmer till the mango pieces have turned soft completely and the water has reduced a bit thus, dissolving the sugar.
Turn off the heat and allow this to cool completely before serving. Best served chilled.
