Boil potatoes in any way you prefer (stovetop, pressure cooker, instant pot, or microwave). I generally place a trivet in a pressure cooker filled with enough water and then place the bowl with potatoes and pressure cook for 3 to 4 whistles. After the pressure releases naturally, peel the skin of the potatoes, roughly chop if needed, and keep them aside
4 Medium Potatoes
In a pan, add oil, coriander seeds, cumin seeds, fennel seeds, and hing, and saute till this sizzles on medium flame.
2 tablespoon Oil, 1 tablespoon Coriander seeds, 1 teaspoon Cumin seeds, 1 teaspoon Fennel seeds, 1 pinch Asafoetida
To this, add ginger and green chilies and saute for another 30 seconds to 1 minute.
1 tablespoon Ginger, 2 Green chilies
Now add potatoes, green peas, garam masala, chaat masala, red chile powder, salt, and coriander leaves, and using a potato masher, nicely mash till everything is well combined.
¾ cup Green peas, ½ teaspoon Garam masala, ½ teaspoon Chaat masala, ½ teaspoon Red chile powder, ½ to ¾ teaspoon Salt, 1 tablespoon Cilantro
Switch off the flame and let the mixture cool.
