Mor kuzhambu with onion is an easy and delicious South Indian buttermilk curry for rice. In this recipe, I have shared my mom’s style mor kulambu made with sour curd, coconut paste, and sambar onions. It tastes great with hot rice and potato fry!

I love our South Indian/ Tamilnadu style mor kuzhambu for rice. Its the simplest, easiest, hassle free curry that can be prepared in no time. I usually follow my mil’s method. For a change, I tried my mom’s style mor kulambu with onions.
My mom never adds turmeric powder but I used here for a nice color. My mom always add masala vada in this kuzhambu. That gives an additional flavor and taste. Sometimes she adds lady’s finger/ vendakkai too. But I dint add any vegetables. I just added onions and made it simple. I enjoyed with hot rice and carrot-beans poriyal. Slurppppp.. it was yummy!
Quick Notes for US & Abroad Kitchens
- Yogurt / Curd: In the US and abroad, you can use plain whole milk yogurt (desi dahi) or Greek yogurt whisked with equal amount of water. For a good traditional sour taste, keep the yogurt outside at room temperature for 3 to 4 hours before cooking.
- Besan Flour: Adding 1 tsp of besan flour mixed with water is very important. It prevents the buttermilk from separating or curdling when heated.
- Stovetop Heat Control: On electric coil or glass-top stoves, keep the flame on low to medium. Never let the mor kuzhambu roll boil; remove it from the burner as soon as it raises and turns frothy.
- Coconut Oil: Tempering in coconut oil gives the authentic South Indian aroma, but regular cooking oil can also be used.
- Variations: You can also add sautéed lady’s finger (vendakkai), cooked ash gourd (poosanikai), or dunk masala vadas into the kuzhambu.

Notes

- Roll boiling makes the gravy watery and lose all its taste. Hope you all know this.
- Do not close the bowl completely. It will also make the gravy watery.

Frequently Asked Questions
