Cut the peeled potatoes into thin chips and rinse them under cold water to remove excess starch. Pat them dry with a towel.
Fry the Chips: Heat the vegetable oil in a deep frying pan over medium heat. Add the potato chips in batches and fry until they are golden and crisp. Remove them with a slotted spoon and place them on a paper towel to drain excess oil.
Make the Masala: In a large mixing bowl, combine the cumin seeds, coriander powder, turmeric powder, garam masala, chilli powder, garlic powder, ginger powder, and salt.
Add the fried potato chips to the mixing bowl and toss them well, ensuring they are evenly coated with the masala mixture.
Transfer the masala chips to a serving plate. Garnish with freshly chopped coriander leaves if desired and serve with lemon wedges. Enjoy your spicy and tangy Masala Chips!
