In a microwave safe bowl add the grated mango, turmeric powder & salt. Mix & allow it to sit for 15-30 mins.
Add tablespoon of sugar at a time & mix till sugar is completely dissolved before adding the next tbsp. Continue stirring till the sugar is completely dissolved.
Now microwave on high for 3 mins. Remove, stir and then microwave for another 3mins. Allow to cool completely. You should get a one thread like syrup consistency. The syrup will thicken over period of time.
Add the roasted cumin seed & red chilli powder. Mix well.
Allow to cool completely and then transfer into air-tight clean container.
The sourness of the raw mango varies so adjust the sugar accordingly. Mine were not that sour so 1 cup sugar was just perfect, if yours are too sour add more sugar
