Mango Kalan
1 ripe Mango, cut into bite-sized pieces
1 pinch Chilli powder
1 pinch Turmeric Powder
3 tbsp Shredded Coconut
1 tbsp Cumin
2 Green Chillies
11/2 cups Buttermilk
Seasoning:
1 tsp Mustard Seeds
2-3 Red Chillies
3-4 Curry Leaves
1 pinch Fenugreek Seeds
Cook the mango together with the chilli powder, turmeric and salt in a little water. Separately, grind the coconut, cumin and green chillies.
Add the ground mixture to the cooking mango.
Allow it to come to a boil. Turn off the heat and add the buttermilk.
In a separate pan, add some oil and add the ingredients for the seasoning. When the mustard seeds start to splutter, add the seasoning mixture to the mango curry.
