Fish in Mustard Sauce

I have it on hearsay that this is a traditional recipe from the coast of Bengal. Flavourful of spicyness with very little heat. Best served with plain steamed/boiled rice and a cucumber raita on the side. Use fish of your choice. *After the first review, the correction related to the first "eleven" ingredients was effected. The recipe itself was obtained from an Indian chef at an international convention. Having enjoyed the dish myself, and having made it subsequently, I posted this on Recipezaar. Being equally perplexed after the first review, I researched the Bengali fish dishes and found essentially the same recipe cited elsewhere. The only advice I can offer is: 1. Do not try the recipe if you equate spiciness with heat and expect the mustard sauce to be anything like the Western commercial mustards. 2. If your sauce and taste preference leans towards the traditional Indian dry "khaari's," this dish will not appeal to you.
