The soul of the broth. Rendered kidney fat (板油) or omental fat (网油) from cattle, pale gold in colour, rich in saturated fats that carry fat-soluble capsaicin and sanshool molecules. Without tallow, the mala heat does not bloom or coat the mouth.
The flavour backbone. A 3–5 year fermented paste of broad beans (蚕豆) and red chillies from Pi Xian county, Sichuan. Contains complex Maillard compounds, glutamates and free amino acids developed during fermentation. No substitute delivers the same depth.
Two varieties work in tandem: Erjingtiao (二荆条) contributes fragrance and deep colour (high ASTA value); Facing Heaven pepper (朝天椒) contributes intense fiery heat. Together they create the La dimension of mala.
The only ingredient responsible for the Ma (麻) numbing sensation. Contains hydroxy-α-sanshool, which blocks K2P ion channels in sensory neurons and triggers TRPV1/TRPA1 simultaneously, creating the distinctive ~50 Hz tactile illusion. Grade 1 (≥1500 SPNU/g) is used in premium broths.
Two fermented umami boosters added in small amounts. Douchi (豆豉) are whole soybeans fermented and dried — intensely savoury with glutamate. Laozao (醪糟, sweet fermented rice wine) adds a low background sweetness that rounds the broth and softens the edge of the chili. Used together they prevent "one-note" heat.
The aromatic foundation fried in tallow before any other ingredient. Old ginger (老姜, 老 = aged, more pungent) contains gingerols and shogaols that suppress nausea and "lighten" the heavy tallow on the palate. Large scallion (大葱) or leek adds a sweet sulphurous undertone.
Added in smashed whole cloves after the ginger-scallion step. Garlic's allicin converts to dozens of aromatic sulfur compounds during frying that provide the broth's characteristic pungent nose. Caramelised garlic also adds sweetness.
A small bundle of whole spices: star anise (八角), cinnamon bark (桂皮), black cardamom (草果) and bay leaf (香叶). Added after the aromatics and simmered slowly. These contribute woody, camphor and licorice notes that give Chongqing broth its distinctive "layered warmth" behind the mala heat.
A very small amount of rock sugar added toward the end. Functions as a flavour bridge: sweetness at low concentrations does not register as sweet — it suppresses bitterness from chili seeds and burnt aromatics, and gives the broth a slight gloss.
Salt calibrates overall salinity; MSG (monosodium glutamate) enhances umami and allows salt to be reduced. MSG is permitted in hot pot soup bases under GB 2760-2014 with no fixed upper limit ("quantum satis") — it is naturally present in all fermented ingredients in the broth anyway.
The Cooking Sequence
The order is everything. 1 → Heat tallow to 120°C in a wok. 2 → Fry ginger + scallion (爆香). 3 → Add garlic, fry golden. 4 → Reduce heat to 80°C; add doubanjiang, stir continuously 30 min. 5 → Add douchi + laozao. 6 → Add dried chillies. 7 → Add Sichuan pepper last (sanshool degrades at high heat). 8 → Add spice bundle; simmer 20 min. 9 → Rock sugar + salt + MSG to finish. The finished base is cooled, pressed and sold as a block — or added directly to the soup pot with water or bone broth.
