Cook Illish Barishali and Serve
Now, heat up some mustard oil in a pan, and let's give it some flavor by tempering it with nigella seeds. Once the oil is hot and fragrant, pour in our mixture and add some water to get things going. Once it starts bubbling away, it's time to gently add in our marinated fish chunks.
Once our gravy reaches the desired consistency, let's add a bit of oil and let it cook for another 2 to 3 minutes to enhance the flavors and serve.
