Mackerel is a famous oily fish curry in Indian cuisine. If you are looking for a sustainable variety to replace your consumption of popular fish, then mackerel is a good substitute for tomato-based curries.
2 Tablespoons oil, preferably coconut oil or vegetable oil
1 lb cleaned and deboned mackerel fish (approximately 3 pieces)
6-7 curry leaves, optional
1 leek, only white pieces, chopped
1 bottle of Rupen's Masala (homestyle curry) sauce
In a 3 qt Dutch oven over medium heat, add oil.
When the oil is hot, add the fish pieces along with the curry leaves and cook for 2 minutes on each side. Remove the fish pieces with a slotted spoon and set aside.
Add leeks to the remaining oil and saute for five minutes.
Add Rupen's Masala (homestyle curry) sauce and bring it to a simmer.
Gently add back the fish pieces, cover and simmer for 7-8 minutes. Serve.
