Transfer rice flakes to a bowl. Soak them in approximately 1 cup of water for 1 – 2 minutes. Be gentle to avoid breaking the flakes.
Discard the water. Transfer rice flakes to a colander. Let the water drain thoroughly.
Add turmeric powder. Mix nicely to coat each piece of rice flake with it.
Heat half of the oil in a kadhai over medium heat. Once oil is hot, add diced potatoes, fry and cook them till fully cooked. Transfer them to a plate and keep aside.
Heat remaining oil in the same kadhai. Add cumin and mustard seeds. Once they start spluttering, add peanuts, green chilli, and curry leaves. Fry for 1 – 2 minutes.
Next add onion and fry until they turn translucent.
Add the soaked poha to the kadhai along with fried potato, salt and sugar. Gently toss it until the poha is evenly coated with the spices. Be careful not to make it mushy.
Now, add lemon juice, and chopped coriander leaves. Turn off the heat.
Let kanda poha sit covered for 2 – 3 minutes for rice flakes to absorb all the flavour. Garnish with fresh coriander leaves.
Serve Kanda Poha hot with a wedge of lemon for that extra tangy kick.
