Add potatoes to a large pot of salted water and bring to a boil. Optional - add a pinch of turmeric to give the potatoes a nice rich yellow colour. Boil until fork tender. About 15 minutes. Drain and set aside.
In a large frying pan or wok, heat the oil. There should be enough to coat the bottom of the pan.
Add the cumin seeds and allow them to cook for 30 seconds and start to sizzle.
Add the boiled potatoes and gently stir to coat in the cumin oil. Being careful not to break up the potatoes too much.
Allow to cook on medium low heat undisturbed for a few minutes. This will allow them to start to turn golden and crisp.
Gently stir and cook for a few more minutes to get golden brown.
Sprinkle with salt to taste. Serve immediately with a sprinkle of chopped fresh cilantro.
Notes
Optional - add sliced green chillies to the cumin oil to give these potatoes more of a kick. Another optional flavour add-on - add a sprinkle of amchoor - dried mango powder at the end with salt for an added tangy flavour.
