Add ground coconut, buttermilk to the vessel containing cooked potato and mix well. (If it is yogurt/curd, put it in a mixer for few seconds before adding it to sasive.) Add water and salt if required.
Put oil, 1/2 tsp mustard seeds, broken red chillies in a pan and heat. Once it starts spluttering, add curry leaves and keep it for few seconds and then add it to sasive. Mix well before serving. It goes well along with rice.
