Leshan Bobo Ji: The Chemistry of Cold Chili-Oil Steeping and Sichuan Aromatics

Hailing from the riverine city of Leshan, Bobo Ji is a vibrant branch of Sichuan street-food culture that redefines cold appetizers. Named after the traditional terracotta pot ('Bobo') in which it is served, this dish utilizes a sophisticated cold-steeping process to extract subtle aromatic nuances from intense spices. Diverse bite-sized ingredients—ranging from tender chicken skin and duck gizzards to crisp lotus roots—are meticulously skewered, poached at controlled temperatures to preserve their ideal crunch, and instantly shocked in ice water. The skewers are then submerged for thirty minutes in a deep crimson bath of clear chicken stock fortified with an artisanal, herb-infused red chili oil and fresh green Sichuan peppercorns. Dusted with toasted white sesame seeds, every bite offers a refreshing contrast where a cooling, crisp physical crunch meets an addictive, tongue-tingling wave of numbing heat.
