Here is yet another this is a typical maacher jhol (bengali style fish gravy) prepared with potatoes and cauliflowers. It is very light on the stomach and is relished with plain steamed rice. I like mine with a dash of lime. In this recipe i have used bata maach, which is a fresh river water fish and is generally relished by most of the bengali crowd. In the absence of it, you can pretty much use any small fish to prepare this gravy. This type of thin gravy is generally served to small kids (with boiled & mashed rice), pregnant women and also to the elderly as it is mildly spiced. Fish has omega 3 fatty acids, vitamins, calcium, magnesium, etc. So it is a healthy choice.
