1. If you don't have any of the hot chilli sauces you can soak around 12-15 Kashmiri or Bedgi chillies in hot water for 15 mins and then grind them to a fine paste. This is an easy substitute.
2. We used semi sweet mangoes that were slightly sour. So we used around 9 teaspoons of muscovado sugar which is not very sweet & has a deep, rich flavour. If you are using white sugar you will need lesser quantity.
3. You can also use raw mangoes for this recipe. Adjust the sugar accordingly.
