In a large skillet, over medium-high heat, heat the oil and add the cumin seeds. Cook them until they start to crackle
Add the potatoes and pan-fry them until they start to brown, reduce the heat, put the lid on, and cook them for 10 mins or until they are tender
Once the potatoes are cooked, add the chilli paste, turmeric, garam masala, lime juice, and salt to taste. Cook for a couple of minutes until all flavors are well combined, remove from heat, and add the fresh cilantro.
