Red braising is basically the Chinese version of braising in wine, except you use soy sauce and sugar. The ribs simmer for a couple hours with star anise and Sichuan peppercorns until they're falling apart, then you reduce the braising liquid into this shiny, sticky glaze.
Place ribs in pot with cold water, bring to boil for 3-5 minutes until scum rises.
Drain and rinse ribs thoroughly under cold water.
In Dutch oven, combine blanched ribs with soy sauces, oyster sauce, brown sugar, garlic, scallions, Sichuan peppercorns, star anise, and chicken broth.
Bring to simmer, reduce heat, cover and cook 1.5-2 hours until meat is very tender.
Remove ribs and strain sauce through fine-mesh sieve.
Boil strained sauce 5-7 minutes until thickened to glaze consistency.
Return ribs to sauce, toss until coated and glossy.
Notes
Liquid should mostly but not completely cover ribs during braising. Stir occasionally to prevent sticking.
