Once you have boiled the potatoes, peel them and chop them into cubes. Set it aside.
Heat oil in a pan on medium heat. Once the oil is hot add the cumin seeds, let them sizzle. Immediately lower the heat so that cumin seeds don't burn.
Then add the crushed coriander seeds and hing (if using) and saute for few seconds.
Add the green chili and ginger and saute for a minute until the ginger starts changing color.
Add in the boiled and cubed potatoes to the pan and toss with the spices.
Add turmeric, red chili powder and salt. Toss to combine potatoes with all the spices.
Let the potatoes cook for 2 to 3 minutes on medium heat, then add the chopped cilantro.
Squeeze in fresh lemon juice to finish it off.
Serve it with roti. I will send you a short video of how we make roti tomorrow.
