Buttermilk curry | Mor Kulambu Onam Special

Onam Sadhya recipe includes 24 to 64 varieties of dishes, including curries, pickle, payasam/kheer, stir fry. One of the dishes is Buttermilk curry | Mor Kulambu | Moru Curry | Pulissery. A buttermilk based curry that includes coconut paste along with spices. The curry is tempered with chillies, curry leaves and mustard seeds. The traditional food of Kerala includes this curry is simple home-style meals. The curry is sometimes made without any vegetables. The generic vegetables used are okra, yellow pumpkin, drumstick, peas and potato, taro roots, brinjal, chow chow, Manathakali Vatral, Sundaikkai Vatral.

This is one among the dishes which will warrant less time and simple methods. Healthy and comfortable food is usually prepared on hot sunny days to cool down the heat. Most of the vegetables used in this curry also help to beat down the hot weather. I prefer to add Okra and ash gourd, chow chow and cucumber. This curry made with curd is very comforting and smooth to your stomach with mild spices and less oil. The same recipe is also made around Tamilnadu with little variations based on the regions. In some places of Tamilnadu, roasted dals are powdered and added to the curry. I am making the curry in Kerala style with coconut paste.

What do we need to make Buttermilk curry | Mor Kulambu Onam Special


A sour Indian style curd yoghurt is the main and important non-compromisable ingredient. If the curd/yoghurt is not sour enough the curry won’t taste good.


Fresh/frozen coconut needs to be ground into a smooth paste along with cumin, chilli, turmeric. I added the turmeric separately in this recipe.


The major spices we use are mild in their spiciness and we used chilli, curry leaves and mustard for tempering.


I used Okra in this curry. Ash gourd, cucumber, chow-chow (Chayote) can also go well along with this curry because of its water content.
