5 small Thai eggplants, stemmed
5 shallots, peeled

Directions
Preheat the oven to 375º. On a clean cutting board, cut the fish into 2 skinless fillets, reserving the head and bones. Refrigerate the fillets until ready to use.
In a medium saucepan, heat the vegetable oil over medium-high heat. Add the reserved fish head and bones with the makrut lime leaves, lemongrass and galangal. Sweat until aromatic, 5 minutes. Add the water, fish sauce and sugar. Bring to a boil, then reduce the heat to a simmer and cook for 45 minutes.
Meanwhile, heat a cast-iron skillet over high heat. Cook the eggplant, shallots, garlic, chiles and jalapeños, turning often, until slightly charred, 5 minutes. Transfer the vegetables to a large piece of aluminum foil set on a baking sheet and fold the edges to form a pouch. Place the baking sheet in the oven and roast until the vegetables are tender, 35 to 40 minutes.
Once the stock has finished cooking, strain and return to the pot. Bring to just below a simmer and poach the reserved fish fillets until opaque, 5 to 6 minutes. Gently remove the fillets from the pot and lay out on a plate.
Transfer the roasted vegetables to a large mortar and pestle. Roughly mash the vegetables with the lime juice, then season with fish sauce. Add the fish fillets and flake the flesh into large chunks.
Spoon the mixture into a serving bowl and garnish with cilantro. Serve with sticky rice, sliced green cabbage and steamed broccoli.
