Sindhi Fish Curry Sindhi fish (machi) curry is also known as raswali machi. Sindhi machi curry is very easy to prepare and onions are not used in this curry. This curry is entirely different from my other fish curries. The blend of tomatoes and coriander leaves along with spices has given a lot of flavour and taste to the curry. I have used pomfret fish steaks to make this delicious Sindhi fish curry.
