To begin making the Chettinad Style Urulai Roast Recipe, boil the potatoes in a pressure cooker with the skin on for about 4 whistle. Release the pressure naturally and drain the water. Peel off the skin and keep it aside. 

Heat a small skillet, dry roast all the Chettinad masala spice including coconut, curry leaves, dry red chillies, cloves, cardamom, cinnamon stick, whole black peppercorns and coriander seeds. Let it cook for about 2 minutes.

Allow it to cool and ground them into a smooth paste by adding little water. 

Heat a kadai, crackle the mustard seeds and cumin seeds. Add curry leaves and let it sizzle and the add the onions, garlic and ginger. Cook till the onion becomes translucent. 

Then later add the tomatoes and a bit of salt and smash it till the tomatoes get cooked. Now add the boiled baby potatoes and let it cook for about 10 minutes. 

Then finally add in the Chettinad ground masala and saute till Urulai Roast gets evenly coated and all the water gets absorbed.

At the end add a little bit jaggery, tamarind paste and check for salt. Give the Urulai Roast a stir and cook for about a minute or two.
