This is a recipe for fish cooked in a mustard based curry sauce. Traditionally, it's cooked using mustard oil, and for the curry, the black mustard grains are soaked in water and then ground over a flat grinding stone, using a stone rolling pin kind of a thing. It basically acts as a pestle and mortar. The use of mustard oil and freshly ground mustard makes it very strong and pungent. But not this one. I've altered the ingredients and added a few extra by using whatever is available, and thus altered the flavour into a milder but flavourful curry.
