Iraqi Masgouf with Slow-Grilled Carp, Tamarind Marinade, Charred Tomatoes and Pickled Mango Amba

Make the amba a day ahead: heat oil in a small pan, add mustard seeds and let them pop. Add fenugreek, turmeric, garlic and chili flakes. Cook 30 seconds. Add diced mango, vinegar, sugar and salt. Cook over low heat for 10 minutes until the mango softens but holds its shape. Cool and refrigerate overnight — amba intensifies as it sits and benefits from at least 24 hours.

Ingredients

• For the fish:
• 1 whole large freshwater carp (about 2kg / 4.4 lbs), butterflied open through the back with skin and head intact — substitute whole snapper, branzino or trout
• Have your fishmonger butterfly it from the dorsal spine so the fish opens like a book
• For the masgouf marinade:
• 3 tbsp olive oil
• 2 tbsp tamarind paste — concentrate, not pulp
• 2 tbsp pomegranate molasses
• 1 tbsp tomato paste
• 1 tbsp baharat (Iraqi seven spice)
• 1 tsp ground turmeric
• 1 tsp sweet paprika
• 1 tsp salt
• Juice of 1 lemon
• 4 garlic cloves, crushed to a paste
• For the charred vegetables:
• 4 ripe Roma tomatoes, halved
• 2 medium onions, halved with skins on
• 2 long green chilies
• Olive oil for brushing
• For the amba (Iraqi pickled mango sauce):
• 1 large slightly underripe mango, peeled and diced
• 1 tbsp fenugreek seeds, soaked in water overnight then drained
• 1 tsp ground turmeric
• 1 tsp mustard seeds
• 2 garlic cloves, minced
• 60ml (1/4 cup) white vinegar
• 1 tbsp brown sugar
• 1 tsp salt
• 1 tsp chili flakes
• 60ml (1/4 cup) neutral oil
• For serving:
• Iraqi tannour bread or large flatbreads
• Fresh parsley, cilantro and dill — large handful of each
• Sliced raw onion and lemon wedges
• Pickled vegetables (turnip, cucumber)

Instructions

1. Make the amba a day ahead: heat oil in a small pan, add mustard seeds and let them pop. Add fenugreek, turmeric, garlic and chili flakes. Cook 30 seconds. Add diced mango, vinegar, sugar and salt. Cook over low heat for 10 minutes until the mango softens but holds its shape. Cool and refrigerate overnight — amba intensifies as it sits and benefits from at least 24 hours.
2. Make the marinade: whisk together olive oil, tamarind paste, pomegranate molasses, tomato paste, baharat, turmeric, paprika, salt, lemon juice and garlic into a thick paste.
3. Marinate the fish: open the butterflied fish flat, flesh side up. Brush the marinade generously over the flesh, pushing into all crevices. Do not marinate the skin side. Let stand at room temperature for 30 minutes — the marinade should fully penetrate.
4. Build the fire: traditional masgouf uses an open wood fire of apricot or tamarisk wood. Use hardwood charcoal as substitute. Build a hot fire with no flames — only glowing coals. Set up two zones: a hot zone directly above the coals and a cool zone with no coals beneath.
5. Cook upright (the masgouf method): traditionally the butterflied fish is staked vertically beside the fire and cooked by radiant heat. For home grilling, place the fish skin-side down on the cool zone of the grill. Close the lid. Cook for 35-45 minutes — never turning the fish. The skin slowly chars and crisps while the flesh cooks gently from above by reflected heat. The fish is done when the flesh is opaque, flaky at the thickest point, and the skin is deeply blackened and crisp.
6. Char the vegetables: while the fish cooks, brush tomatoes, onions and chilies with oil and char them directly over the coals or hot zone for 5-7 minutes per side, until blackened and softened.
7. Final char: in the last 5 minutes, brush the fish flesh with any remaining marinade and slide it briefly into the hot zone to deepen the color and char.
8. Serve communally: transfer the whole fish to a large platter. Surround with charred tomatoes, onions and chilies. Lay flatbreads beside it. Serve with bowls of amba, raw onion slices, fresh herbs and lemon wedges.
9. Eat the masgouf way: tear off pieces of the smoky flesh with the bread, top with herbs and a swipe of amba, and roll into a wrap. The combination of charred tamarind-glazed fish, sour-spicy amba and fresh herbs is the defining flavor of Baghdadi cuisine.
10. Masgouf is the national dish of Iraq and one of the world's oldest documented recipes — references to grilled Tigris carp date to Mesopotamian clay tablets from the second millennium BCE, making it possibly the oldest continuously prepared fish dish in human history. Baghdad's Abu Nuwas Street, running along the Tigris, has been home to masgouf restaurants for centuries; diners traditionally select their carp live from tanks, watch it be butterflied and staked, and eat the finished fish at outdoor tables along the river. The pomegranate-tamarind glaze is an ancient Mesopotamian flavor combination, and amba — derived from the Persian word for mango — entered Iraqi cuisine via Iraqi Jewish merchants who traded with India in the 19th century and brought back the pickled mango tradition.
