Notes
Bhindi needs a little extra oil to cook, otherwise it becomes stiff when cooked. So, do not compromise on the quantity of oil.Bhindi must be totally dry; otherwise, it becomes slimy when cooked. I like to wash it the night before I plan to cook it. This way, any moisture in it evaporates and is ready to cook. If you haven't planned it this way, then wipe each piece with a cotton cloth.Cut the bhindi into equal-sized rounds so that it cooks evenly.
