How to cook Rohu fish in Bengali style?

For as long as I can remember, fish has been a compulsory side-dish for lunches at home. There would be rice accompanied with a serving of dal or lentils, a sabji or vegetable side dish and a fish to fulfil our daily protein need.

Though we have a wide range of Bengali fish recipes to choose from. For regular meals, most of the time we would get Rohu or rui mach. Reason being its availability in abundance at much cheaper rates.

There is no getting around this fact that we Bengalis cannot live without our daily share of fish in our meals. So, at one point of time it becomes imperative to look for a source of protein that is easily available and equally good in taste.  Rui mach or rohu fish ticks all boxes in the criteria list. This riverine fish is sweet in taste and perfectly complements the flavors it is cooked with. Whether it is the pungency of mustard seeds or tartness of yogurt, this fish is the man-friday of all.

This Bengali steamed mustard fish recipe is probably one of the easiest as well and can be cooked within 20 minutes tops. Needless to say, it has saved me on many hurried mornings or when I am expecting guests at short notice.

Bhapa Rui mach recipe ingredients

This rui mach bhapa recipe is so healthy and absolutely fuss-free. You can either steam it on your stove-top steamer or cook it in your microwave oven. Both ways, it is absolutely delicious!

To start with we need to clean the fish pieces and make sure that there are no scales on them. Then rub some salt and turmeric powder on them. Keep it so for at least 30 minutes or so while we prepare the mustard gravy for this bhapa rohu recipe.

Grind the poppy seeds first till its a white smooth paste. I have used my NutriBullet here which is perfect for grinding small quantity ingredients like poppy seeds perfectly. Only then add the mustard seeds and give it a quick buzz a couple of times. This is to avoid them turning rancid by over grinding.

These mustard seeds & poppy seeds are going to be the base of the gravy of this bhapa rui mach recipe. Mix the rest of the ingredients and some water to create the gravy.

Finally, lay down the pieces of fish in a baking dish and pour the gravy on them. See that they are well submerged. Finally drizzle some mustard oil if you are partial to the pungency of raw mustard oil just as we are. Place a couple of sliced green chillies before sealing the dish with some clingfilm sheet. Poke a couple of holes in the clingfilm so that it doesn’t burst open while cooking in the Microwave oven.

If you can get a few Kafir lime leaves or Kafir limes (Gondhoraj Lebu), then you can use it as well. Place the leaves on top of the fish along with the chillies and you will get a wonderful aroma to this dish. In case of lemons, just drizzle some of its juice on the top.

It is my absolute guarantee that in next 10 minutes you will have some delicious rui mach bhapa, ready for your dinner table!

Make-ahead or Freezing Option for this Rui Macher Bhapa recipe

You can easily make a double batch of this bhapa rui mach in Microwave oven. This dish has very little gravy to it, hence a longer shelf life. In fact, this rui maach bhapa recipe tastes even better the next day after it has rested in that gravy and soaked in all the favors for over a day.
