Rub cod chunks in turmeric, cumin, coriander, salt, and pepper. Pan-fry until golden on both sides. Set aside.
In the same pan, sauté onions until soft. Add garlic and spices (cardamom, cumin, black pepper), cook 1 min.
Add loomi powder, coriander, dill, chilli, and chopped tomatoes. Sauté 5 min until tomatoes soften.
Add tomato paste and stock. Bring to a boil, then simmer 10 min.
Add okra and simmer 10 min. Don't stir too much — excess agitation makes okra release slime.
Nestle the fried cod into the stew. Simmer gently for 15–20 min until the fish is cooked through and has absorbed the stew flavors.
Over vermicelli rice or with pita.
Loomi (dried black lime) is the soul of this dish — it gives the stew its distinct sour, earthy depth. Find it at Middle Eastern or Persian grocery stores.
