Mix the hake steaks with salt and a little bit of turmeric powder and set aside.
In a small bowl mix all the ground spices with a little water and set them aside.
Put a large pan with oil on medium-high heat. When the oil is hot, add the bay leaf and cumin seeds. Add onions and fry them until golden brown.
Add ginger paste and sauté for few seconds. Then add the spice mixture and tomatoes. Fry everything together until the oil separates.
Add one and half a cup of water or fish stock.
Add the hake steaks and salt. Let them simmer for 7 minutes. Then turn them over very carefully so that they do not break and let them cook for another 7 minutes.
Serve them with hot basmati rice.
