wow! dhathoori gida - this used to be all over our area in Srinagar (blr), when we moved there 20 years ago.
hitthala gida madhdhalla...
we used to cut the leaves and use the white milk kind of solution for some reason, that i can't recall now.
those flowers and leaves were required for ganesh pooja, so we used to go into the fields early in the morning to get some from the thorny plant.
These plants are no longer available in that area these days...
