You can add or reduce the qty of raw mango, depending on its sourness. I use Maggi coconut milk powder. For 1 cup of thick coconut milk, add 3 heaped tbsp of coconut milk powder to 1 cup of water and for 1 cup of medium thick coconut milk, add 2 heaped tbsp of coconut milk powder to 1 cup of water. You can adjust the qty of coconut powder as per your requirements.
