Heat oil in a pan & add cumin seeds. Let seeds splitter.
Add green chilli and onion.
Saute onion and let it turn pink and translucent. Note, not to let onion turn brown and hence loose its crunch.
Add red chilli powder, turmeric powder, coriander powder and garam masala. Saute.
Whisk the curd very well and add to the pan.
Immediately start and keep stirring for about a minute or two or until curd begins to boil. Do not stop otherwise curd will crackle down.

When the curd is cooked, add water.
Also add salt.
Let the water come to boil.
Add Mongra, mix it in the curd gravy well.
Boil it for one more time.
Mongra curry is ready.
