I think its true that Bengali's cannot stay away from fish....HAHAHAHA.... :D the best example is my Baba , he really doesn't enjoy food without a fish dish. I too like to have fish ones a month and I love fish fry the most.
One thing I have felt over the years that having fish at home made weekday dinners easy :) . Just one fish dish with some rice or roti and we are done. Well the following recipe is something which I had made after i came from office at 11:00 and believe me by 11:30 I was enjoying my dinner.
