Make the Chhana and knead it to soft ball. Then, add half of the sugar and mix well.
Puree the mangoes and sieve to ensure there are no lumps.
Heat a nonstick pan, add the mango puree and cook till it is done. This takes about 5 to 7 mins on high.
Add sugar and combine well, continue cooking.
Next, add the chhana and combine. Continue cooking for a while till everything is mixed.
Next, add the remaining sugar and let the mix get cooked for another 5 mins.
Do not let the mix overcook, you will end up having a crumbly Sandesh.
If you are going to shape the Sandesh, then press the Sandesh into the mould, let it set at room temperature or refrigerate for an hour or so.
Garnish with finely chopped mangoes, nuts before serving.
