Regulars can tell by taste alone whether a stall's simmering pot has been going for days or weeks — the older the 'mother broth,' the more prized the stall.
Beef lungs, tripe, tendon, and other offal are simmered for hours in a well-seasoned master stock, then ladled into paper cups with chili and hoisin-style sauce, often alongside daikon radish. Street carts keep the same pot simmering for days, topping it up as they sell.
