Poosanikai Mor Kuzhambu | Buttermilk Kuzhambu | Mor Kuzhambu Recipe

Poosanika Mor Kuzhambu

During my sluggish days and when my curd becomes sour, I make this Mor Kuzhambu. What I like about the Poosanikai Mor Kuzhambu is the mild flavor of white pumpkin, and also it is very soft when you bite the white pumpkin.

Very easy to make and no cutting work is needed except for the cutting of white pumpkin pieces. When you do not have onion and tomatoes in kitchen, you can make Mor Kuzhambu. Though I have already posted Cucumber Moru Kootu in my blog, I thought I should also post a different version of Mor Kuzhambu and this time with White Pumpkin. I usually love to have it with Potato Fry, Kovakkai Fry / Tindora Fry, Plantain Poriyal and Brinjal Pirattal. Whenever I have guest at home, I will have this dish as an option. After all, who would not like Mor Kuzhambu?
