Rinse the cluster beans in cool water. Set aside.
In a medium size pot, add the 4 cups of tap water over high heat, bring it to a rapid boil, add the beans, and blanch for 7 to 10 minutes or until beans soften.
Lower the heat, remove the pot, drain the water, and reserve the beans in a colander.
Next in the same pot, over medium heat, add oil and swirl around to ensure the pan is entirely coated with oil. Add the cumin seeds, once it sizzles add onions, jalapenos, tomatoes, and potato cubes; stir well.
Add the blanched beans and sprinkle the cumin and coriander powder and salt (optional) over the mixture, add the remaining cup of water, give it a quick stir.
Cover the pot, lower heat to low-medium setting and cook for thirty minutes or until its cooked and moist.
Once cooked, remove from the stove and transfer into a serving dish; garnish with few cilantro leaves and lemon wedges.
Enjoy the guvar aloo salan.
