Aigir PNG Fish Stew

Aigir is the signature dish of the Tolai people of East New Britain Province (Kuanua language), and the word also names the cooking method itself. Rather than a simmered pot stew, it is cooked by heating stones in a mumu pit and dropping them red-hot into a pot of coconut cream with the food, then sealing it to cook 15-20 minutes. Traditionally made with chicken plus aibika greens, kaukau, corn, onion, and tomato; fish is a coastal variant. Part of the wider Pacific-island coconut-milk tradition and kin to PNG's earth-oven cooking.

Spoon up aigir — fish chunks tender in creamy coconut broth, deep-green aibika wilted around, ginger-and-chili aromatic. Bite: fish delicate, lime-cured surface; coconut milk's tropical creaminess; aibika's earthy-mineral depth; chili tingling. Over rice or kaukau, this is the Morobe coastal evening meal.

Red-hot stones dropped into the pot bring the coconut cream and food to a rapid boil and cook it in 15-20 minutes. Coconut milk is an emulsion stabilized by coconut proteins (mainly globulins and albumins); heating past ~80-90°C denatures and flocculates these proteins, thickening the broth, turning it creamy-white, and releasing some oil that carries fat-soluble aromatics (ginger, chili, onion). A brief lime-juice cure firms and whitens the fish surface. Greens are added late to keep their color and texture.
