Step 2 Prepare the potato filling for Undhi
Put another kadhai over medium flame and heat oil in it. Once the oil is hot enough, add cumin seeds and mustard seeds in it. Let them crackle for a few seconds, then add finely chopped onion, ginger-garlic and green chilli paste. Stir and saute until it’s golden in colour. Now, add boiled and mashed potatoes in it, salt, turmeric powder, and coriander leaves. Mix well and cook for 2-3 minutes. Your stuffing for Undhi is ready.
