A Sichuan dry-pot staple built on pig trotters braised tender in spiced brine, then lightly fried until the skin puckers, then tossed in a blazing-hot wok with doubanjiang, dried chilies, and Sichuan pepper until the sauce clings dry. No broth — just concentrated, numbing-hot flavor. The dish arrives tableside in a cast-iron pot over an alcohol burner; the skin is springy and gelatinous, the meat yields without falling apart, and the sauce deepens with every minute of tableside heat.
Dry-pot pig trotters belong to the Sichuan dry-pot (干锅) genre, which is said to have emerged in the Nanheба district of Mianyang and spread widely after the early 2000s — though Deyang also claims the lineage, and the dispute remains unsettled. Pig trotters, known locally in Sichuan as 蹄花, had long anchored comfort-food traditions like the slow-simmered 老妈蹄花 before dry-pot restaurants proliferated. Once the format took hold, cooks moved the trotter into the dry-pot idiom: after a long spiced braise, the pieces are fried and tossed in a rich doubanjiang-chili sauce, becoming one of the genre's most enduring dishes alongside dry-pot duck feet.
Lift a piece from the pot — the skin is lacquered red with chili oil, yielding but springy under the chopstick. Sichuan pepper numbs first; chili heat and the dark, caramelized notes of doubanjiang arrive a beat later. The whole trotter has taken flavor to the bone. The burner holds the pot at temperature through the meal; the last piece, with the sauce nearly dry-burnt against the iron, is always the best bite.
Two separate heat applications build the dish's layered texture. A long braise in spiced brine hydrolyzes the collagen-dense trotter skin — roughly one-third of pig skin protein is collagen — converting it to gelatin that makes the skin silky and springy without dissolving. A brief hot-oil pass then drives rapid surface dehydration, creating a puckered shell that locks in the gelatinous interior and gives the doubanjiang sauce something to cling to. In the dry-pot toss, capsaicin from the chilies fires TRPV1 pain receptors while hydroxy-alpha-sanshool from Sichuan pepper simultaneously activates low-frequency vibration mechanoreceptors — the familiar 麻辣 double act. The alcohol-burner heat continues reducing the sauce as diners eat, concentrating and intensifying flavor with each passing minute.
Variations
Some versions fold in white kidney beans or celery stalks for textural contrast against the sticky skin; others add fermented black beans or rice wine lees during the braise for deeper sauce complexity. Mianyang-style tends toward extra facing-heaven chilies for a harder punch; Chengdu restaurant versions typically moderate both the numbing and the heat.

How it's made
8 steps · 15 min
- 15 min
Rinse the pig trotters and place in cold water; bring to a boil with ginger slices and Shaoxing wine, blanch 5 minutes, then drain and rinse clean of all blood foam.
- 290 min
Return the trotters to a clean pot; add star anise, Sichuan peppercorn, dark soy sauce, and enough water to cover. Bring to a boil, then reduce to a low simmer for 80–90 minutes until the skin is tender and yields under light finger pressure.
Watch outBraise the trotters low until the skin yields under light finger pressure — that slow cook is what turns the tough skin silky before it ever hits the oil.
- 310 min
Drain the trotters and transfer to a wire rack; rest for 10 minutes until the surface loses visible moisture.
- 45 min
Heat oil to 180°C in a wok or deep pan; fry the trotters in batches for 2–3 minutes, turning once, until the skin puckers and turns golden. Lift out and drain on a rack.
Watch outFry the trotters until the skin puckers and turns golden — that puckered shell locks in the gelatin and gives the sauce something to grip.

In a clean wok over medium heat, add 2 tablespoons of oil; fry the doubanjiang for 90 seconds, stirring constantly, until the oil turns brick-red and the paste smells deeply fragrant.
Watch outFry the doubanjiang until the oil turns brick-red and smells deeply fragrant — that red oil is the flavor base; stop short and it tastes raw.
- 61 min
Raise to high heat; add dried chilies, Sichuan peppercorn, minced garlic, ginger slices, and scallion sections and toss for 30 seconds until the aromatics bloom.
- 73 min
Add the fried trotters, a splash of Shaoxing wine, dark soy sauce, and rock sugar; stir-fry over high heat for 2–3 minutes until every piece is coated and the sauce clings dry to the skin.
Watch outToss over high heat until the sauce clings dry to every piece — a wet, pooling sauce means it hasn't reduced enough.
- 82 min
Transfer to a hot cast-iron dry pot set over a lit alcohol burner; serve immediately and continue eating as the burner reduces the sauce tableside.
