Prep: Have all your ingredients prepped and ready: pork sliced, eggs peeled, peppers chunked, aromatics and sauces measured.
Sear Pork: Place the pork belly slices in a cold, dry wok or Dutch oven. Turn the heat to medium and cook, turning, until golden brown and the fat has rendered (5-7 minutes). Remove pork with a slotted spoon, leaving the fat in the pot.
Fry Eggs & Peppers: Add the peeled hard-boiled eggs and green pepper chunks to the hot pork fat. Fry on medium-high heat, moving them around until the eggs are golden and blistered ("tiger skin") and the peppers are lightly charred (3-4 minutes). Remove and set aside.
Fry Aromatics: Leave ~1 tbsp of fat in the pot. Add all the aromatics (star anise, cinnamon, bay leaves, peppercorns, chilies, ginger, garlic, scallion whites). Stir-fry on medium heat for 30 seconds until very fragrant.
Add Pork & Sauces: Return the seared pork to the pot. Add the light soy sauce, dark soy sauce, oyster sauce, and sweet bean sauce. Stir-fry for 1-2 minutes to coat the pork and caramelize the sauces.
Braise: Add the fried eggs (but not the peppers yet). Pour in the beer and enough water to almost cover the pork. Bring to a boil, then reduce the heat to low, cover, and simmer for 50 minutes.
Add Peppers: Uncover the pot, add the green peppers back in. Continue to simmer (uncovered) for another 10 minutes.
Reduce Sauce: Turn the heat to high. Cook, stirring gently, to reduce the sauce until it's a thick, glossy gravy that coats the pork (about 5-10 minutes). Crucially: Do not over-reduce! Leave plenty of sauce for the rice.
Serve: Serve hot over steamed rice, spooning plenty of the extra sauce over everything.
