Parboil and Clean: Throw your 3 lbs of cut pork riblets into a pot of boiling water for a few minutes to lift all the scum and impurities to the surface, rinse them thoroughly under cold running water, and leave them aside for 10 minutes to dry completely.
Marinate the Ribs: Toss the dry ribs into a large bowl and season them with salt, sugar, chicken bouillon, fish sauce, sesame oil, honey, black pepper, and a spoonful of Char Siu sauce, giving the meat a really good massage to lock in the flavors before covering and chilling in the fridge for a few hours or overnight.
Build the Caramel Base: Heat a splash of neutral oil in a large pan over low heat, drop in 4 to 5 tablespoons of white sugar, and leave it alone to slowly melt into a gorgeous amber caramel before immediately tossing in your minced garlic and shallots to fry until fragrant while keeping them moving so they don't burn.
Sear, Braise, and Reduce: Drop the marinated ribs into the hot caramel pan without crowding them, sear over high heat to lock in the juices, pour in 3 cups of coconut water, and bring it to a simmer to cook covered for 15 minutes before stirring in 2 to 3 tablespoons of Vietnamese chili sauce and letting it braise uncovered for another 20 to 40 minutes until the ribs are falling-off-the-bone tender and the liquid reduces into a sticky, glossy glaze.
