Fish Ambotik/Surmai Ambotik/ Hot and Sour Indian Fish Curry

The best Seafood recipes of Maharashtra come from the coastal belt of Konkan and Malvan.
Though I have been on a seafood staple since childhood, in Mumbai , the best Fish curry I ever had , was this Fish Ambotik , that my elder sister made for dinner, at her In Laws place! She is my true cooking Idol! Its from eating her delicious treats and watching her cook and bake that I developed a liking towards cooking, in addition to being a foodie!
Years later, I still remember that taste ,  and this recipe is an attempt to recreate that magic!
