Poosanikai Mor Kozhambu (Ash Gourd in Spicy Buttermilk Curry)

Poosanikai_Mor_Kozhambu_Ash_Gourd_Buttermilk_Curry_1 Mor Kozhambu is a traditional buttermilk based curry of south India. It uses less oil and chilli. This gives a soothing feeling after eating and suits well for the summer season. The spices used in this curry vary region-to-region and home to home. You can add any veggie in this curry like okra, drumstick, taro and ash gourd. We love this with ash gourd or okra.

Here I have prepared Mor kozhambu using ash gourd. This is prepared with slight variation in north India and they call it as Khadi.

Ash gourd or white gourd is known as Neer Poosanikai in Tamil and as Petha in Hindi. Buttermilk is known as Mor(u) in Tamil.

  • Ash gourd pieces – 1 cup

  • Serve hot with rice.



  • When thick curd is diluted it becomes buttermilk.
  • If buttermilk is too sour, add one more green chilli.
  • Adding salt finally in the dish helps to avoid it to be too watery.
