Bengalis savor every meal and are known to buy vegetables and fish fresh every day for their daily menu. Meals last for hours and preparation is a party in and of itself. This bengali recipe is commonly made for festive occasions. It is a good idea to add it to your repertoire as it is an option that is light and aromatic for a large gathering of friends and family. It is even a suitable choice for weddings. Rohu, a freshwater fish in the carp family extensively found in south asia, is the most common fish used, but, you could also use any other larger fish for the dish. For example, freshwater bass or buffalo carp work well. You might also consider salmon if the other options are not available. Serve with piping hot, plain boiled rice.
