Chongqing Hot Pot Broth Base (Málà)

From an evening at Sister Pei’s Chongqing Hot Pot (珮姐重庆火锅) in Shenzhen on 11 March 2026 — a divided yuānyāng pot, fierce red on one side and clear on the other, a mounded platter of paper-thin beef, and aprons handed out to the whole table because the oil spits.

The thing to understand before you cook this is that málà (麻辣) is two words doing two different jobs, from two different ingredients:

麻 má is NUMBING. That is Sichuan peppercorn, and it is not heat at all — it is a physical buzz on the lips and tongue, closer to a mild electric tingle. 辣 là is HOT, and that is chilli. A Chongqing broth runs both at once, and the balance between them is the style.

The base is a deep bed of beef tallow, dried chillies, Sichuan peppercorns and doubanjiang, fried slowly until it blooms. Beef tallow rather than oil is not a detail — it is the defining fat of Chongqing hot pot, it carries the fat-soluble capsaicin, and it sets solid when cold, which is how the base is stored and sold in blocks.

The other half of the meal, and the part people skip at home, is the dipping bowl. In Chongqing the standard is sesame oil with raw garlic, and its job is not really flavour: it COOLS what you have just fished out of a boiling pot, and it carries chilli oil away from your mouth rather than into it. Ordering a hotpot and then dipping into soy sauce is missing the mechanism.

Ingredients

For the base

• 1 lb beef tallow (rendered beef fat)
• 1/2 cup vegetable oil
• 3 oz dried Chinese chillies (erjingtiao for fragrance, facing-heaven for heat), stems off
• 1/3 cup Sichuan peppercorns (red; add a spoon of green for a sharper buzz)
• 1/2 cup Pixian doubanjiang (broad bean chilli paste)
• 2 tbsp fermented black beans (douchi), rinsed
• 6 cloves garlic, crushed
• 3 inch piece ginger, sliced
• 4 scallions, in lengths
• 2 star anise
• 1 cinnamon stick (cassia)
• 3 bay leaves
• 1 tsp fennel seed
• 2 black cardamom pods
• 1 oz yellow rock sugar
• 1/4 cup Shaoxing wine

For the pot

• 8 cups unsalted chicken or beef stock

For each dipping bowl

• 3 tbsp sesame oil
• 2 cloves garlic, minced
• Salt, and chopped coriander and scallion to taste

Directions

Key ingredients

Rock Sugar · Salt · Cinnamon

1. Soften the chillies: Simmer the dried chillies in water 5 minutes until pliable, drain, then blitz to a coarse paste (ciba chilli). This is what gives the base its body and colour without burning.
2. Render and warm the fat: Melt the beef tallow with the vegetable oil in a heavy pot over low heat.
3. Aromatics first, and take them OUT: Fry the ginger, scallion and garlic in the fat over low heat for 10 minutes until browned and the fat smells of them, then fish them all out and discard. They have done their job and will burn later.
4. Doubanjiang, low and slow — this is the step that matters: Add the doubanjiang and fry over LOW heat for 15-20 minutes, stirring often, until the fat turns deep red and the paste smells sweet rather than raw. Rushing this on high heat scorches it and the whole base turns bitter with no way back.
5. Add the chilli paste: Another 20-30 minutes on low, stirring. The fat will separate and go brilliant red.
6. Spices and wine: Add the whole spices, black beans and rock sugar, then the Shaoxing wine. Cook another 15 minutes.
7. Sichuan peppercorns LAST: Add them in the final 10 minutes. Their numbing compound is volatile and long cooking drives it off — this is the single most common mistake and it is why some homemade bases are hot but not numbing.
8. Rest it: Cool and leave overnight if you can. It improves noticeably, and it sets solid, which is how you store it.
9. At the table: Melt a generous scoop of base into the stock, bring to a simmer, and cook at the table. Cook a few pieces at a time — seconds for paper-thin beef, minutes for potato or tofu.
10. Mix each dipping bowl: Sesame oil, raw minced garlic, a pinch of salt, coriander and scallion.

Notes

Provenance: Eaten at 珮姐重庆火锅 (Sister Pei’s Chongqing Hot Pot), Shenzhen, 11 March 2026, 18:10-19:27. The photograph is my own, of the divided pot on our table. The recipe is a standard working formula for the style — it is not that restaurant’s base, which is a closely held commercial recipe.

Beef tallow is not optional if you want the real thing. It is the defining fat of Chongqing hot pot and behaves differently from vegetable oil — it sets, it clings to the food coming out of the pot, and it carries the chilli. A vegetable-oil base makes a perfectly good spicy hot pot; it does not make this one.

The yuānyāng (鸳鸯) divided pot is social technology, not culinary. ‘Mandarin duck’ is Chinese shorthand for a pair, so a yuanyang anything means two unlike things joined. It exists so a table with different heat tolerances can eat the same meal without anyone having to negotiate or opt out — which is exactly why it was on our table, a group of visitors and hosts with no shared baseline.

Erjingtiao chillies for fragrance and colour, facing-heaven (chao tian jiao) for heat. Most good bases use both. If you can only get one, erjingtiao gives a more interesting base and you can add heat separately.

Numbing fades in storage. The base keeps for months refrigerated or frozen, but the má goes off faster than the là. Freshen it by adding a spoonful of freshly ground Sichuan peppercorn to the pot at the table.

Order of cooking at the table: start with things that flavour the broth (mushrooms, meatballs), leave leafy greens and anything delicate until later, and cook offal and thin beef in seconds rather than minutes.

The aprons are real. Sister Pei’s hand them out to every customer, and after ninety minutes leaning over a rolling pot of beef tallow I understood why. Wear an apron.
