Place the potatoes into a large pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender, about 20 minutes. Drain and cool to room temperature.

Once the potatoes have cooled, peel and cut into bite-sized cubes. Place into a mixing bowl, and sprinkle with ground cumin, coriander, amchoor, red pepper flakes, and salt. Toss gently to evenly coat the potatoes with the spices.

Heat the vegetable oil in a large skillet over medium heat. Stir in the whole cumin seeds, and cook until they begin to pop, about 30 seconds. Add the potatoes; cook, stirring occasionally until the potatoes have heated through.
