Mor kuzhambu / mor kulambu is a buttermilk-based gravy. This post is on making Ashgourd / white pumpkin / poosanikai mor kuzhambu.
Mor kulambu is a curd or buttermilk-based curry from the South Indian cuisine and is similar to kadhi from north India. Making mor kuzhambu is easy. Mor Kuzhambu is a recipe that is prepared with ground coconut and green chillies which is then mixed in whisked curd along with a seasonal vegetable. In this recipe, we have used white pumpkin or poosanikai, which is a water rich vegetable, and easy to digest. Ash gourd keeps both our body and mind cool!! The much needed one for the hot summer. The base buttermilk gravy or mor kuzhambu recipe is same, but the choice of veggies can differ as per your taste buds. Ashgourd/poosanikai can be replaced by chow chow/chayote squash or cucumbers/vellarikai or arbi/taro root/seppan kizhangu. Ladies finger/vendaikkai too can be used.
How to make more kulambu with different vegetables
- Okra (lady finger, bhindi, vendaikkai) – sauté in some oil till okra is almost cooked. Then add in the curd mixture.
- Potato (aloo, urulai kizhangu) – boil or pressure cook. Then peel, chop and add in the kuzhambu.
- Drumstick (murungakkai) – scrape or peel, chop and then cook in some water till almost done. Similar to the recipe shared here.
- Brinjal (aubergines, baingan, kathirikkai) – sauté in some oil till cooked. A bit of water also can be added while cooking brinjals.
- Chow chow (seemai kathirikai) – peel and boil in some water till almost cooked. similar to the recipe shared here.
- Taro roots (arbi, seppankilangu) – boil or pressure cook. Then peel, chop and add to the kulambu.
- Spinach or amaranth leaves (keerai) – chop, blanch, mash and then add to the curd mixture.
Every dish has different taste depends upon the veggie we used. Sometimes I prepare with Chana dal-toor dal vada. Prepare vada not too crispy and put it in to mor kulambu. that’s also tastes great. My kids like vada mor kulambu but me and my husband likes very much any kind of mor kulambu. Mostly in Saturdays I prepare this mor kulambu or Paruppu urundai kulambu when we eat with steamed rice, ahaaa … usually I serve with potato pepper curry or green banana fry.
