Peel and slice the mango into large chunks.
Blend the mango, green chillies, ginger, besan and yogurt to a fine puree. Add this to a saucepan and start heating on a low flame, with constant stirring. Add the salt and sugar.
In a small tempering ladle, heat oil. Add the cloves, cinnamon, curry leaves, cumin seeds, red chillies and asafoetida. Once the spices puff up / crackle, add it to the simmering kadhi in the saucepan and allow to simmer on low flame with constant stirring for 3-4 minutes until the kadhi absorbs the flavours from the whole spices.
Remove from flame, cover and keep aside for 30 minutes or so,
Serve with steaming hot rice and ghee.
