Take mustard oil in an iron wok. Heat it up and then let it cool down

Now add whole cumin seeds. Once they crack add nicely washed and cut into halves potatoes and stir nicely

Add salt and stir again

Now cover it properly and keep covered on low flame for 5-7 minutes.

Keep stirring in between till the potatoes are done and add crushed black pepper and chopped coriander leaves in the last stir just before serving to retain the flavour

Enjoy with roti or parantha
