You are going to have dumplings — served either boiled or pan-fried — so start there. The pork and cabbage are the most traditional; the most imaginative are those stuffed with succulent lamb, black bean chili, and whole peanuts and served with a tomato sauce for dipping. Seasoning is generally subtle in the dumplings, but each table has decanters of black vinegar and soy sauce and a pot of arbol chili oil for mixing (in your own personal ramekin) a sauce tempered to your desired heat, saltiness, and umami.
