slightly spicy gravy made with slightly sour Yoghurt / Buttermilk which can be made with different veggies, Here Broccoli is used.
Hints: when using okra and Brinjal fry them with little oil, ( with Brinjal, cut the vegetable to your desired shape and put them in water and keep aside for 10 minutes, this helps in removing the bitterness from the veggie) While cooking use the same method as above and add them as mentioned in the above recipe. If you are using Snake Gourd cut them into little thicker pieces add a tsp of salt and leave it for a while, after an hour or so you can see water released in them drain out the water and wash it once again in water, my mom says the bitterness in it goes away and you need to throw the water and give it a rinse, then use the vegetable for cooking with enough water until it is soft ( I usually cook it in my little pressure cooker for just one whistle it doesn't become mushy).
With other vegetables, after they get cooked no need to drain the water from them but you can add the ground masala and cook together and continue with the same procedure.
