Hakka Stuffed Bitter Melon

Hakka stuffed bitter melon, niang ku gua, is the flagship application of the Hakka niang, or stuffing, technique, in which a vegetable is hollowed and filled with a seasoned minced meat. The Hakka are famous across southern China and Taiwan for their stuffed dishes, stuffed tofu, stuffed eggplant, stuffed peppers and stuffed bitter melon, the technique born of the need to stretch a little meat with abundant vegetables. The bitter melon version is considered the most refined, the melon's challenging bitterness requiring the most skill to balance. The dish is built by cutting bitter melon into thick rings, removing the core and seeds to hollow each ring, blanching briefly to soften and tame the bitterness, then stuffing each ring with a mixture of minced pork, fish paste, dried shrimp, garlic and shallot. The stuffed rings are pan-fried to set the filling, then braised gently in a soy, rock-sugar and water broth until the melon is meltingly soft, its bitterness having dissolved into a gentle, complex sweetness, and the filling's savoury juices having seeped into the broth. Eaten hot with rice, the dish is a Hakka restaurant standard across Taiwan, the transformation of bitter to sweet the point.

A meltingly soft, mild bitter-melon ring, the bitterness having cooked to a gentle sweet complexity, giving way to a savoury, bouncy pork-fish filling, the braising broth deeply savoury and slightly sweet. Comforting, balanced, the bitterness a memory.

The technique is the hollow-and-stuff and the long braise that tames the bitter. Bitter melon is cut into thick rings, the soft core and seeds scooped out with a spoon to leave a clean ring, then blanched in boiling salted water for 2 to 3 minutes, this blanch both softening the melon and leaching out some of the bitter compounds, making the dish approachable. The filling is a mixture of minced pork, fish paste for binding and bounce, soaked dried shrimp, minced garlic, fried shallots, salt, sugar and white pepper, beaten until sticky. Each ring is stuffed full with the filling, the rings pan-fried briefly on both sides to set the filling in place, then a broth of soy sauce, rock sugar, water and a little oyster sauce is poured in and the dish simmered gently for 30 to 40 minutes. The long, slow braise both softens the melon to melting tenderness and transforms its bitterness into a complex, gentle sweetness, while the filling's juices seep into the broth, making it savoury and rich. The transformation of bitter to sweet through cooking is the dish's magic, and the soft, savoury result bears no resemblance to raw bitter melon.
