Luzhu Huoshao (Beijing Offal Stew with Baked Buns)
Slow-simmered pork intestines and lung in a spiced pork-bone broth, with baked wheat buns stewed until they drink the soup, finished with garlic, chilli oil and fermented bean curd. Adapted for a home kitchen from the original ClouChef R&D report — 卤煮火烧, report 87.

Why this works
Luzhu is a dish of patience outsourced to the broth: the report's old stock simmers pork bones for four hours with star anise, cinnamon, scallion and ginger, and that long stock is what carries the offal, not the other way round. At home the honest shortcut is a good pork or chicken stock, because the offal itself is already cooked — the twenty-minute home step is about marrying, not cooking from raw. The buns go in whole, halved, and simmer gently for fifteen minutes: long enough to absorb the broth and swell, short enough to hold their shape, and the broth must stay at a low simmer, never a boil, or they fall apart. Garlic, chilli oil and bean curd go in only in the last two minutes, so their sharpness stays bright against the rich broth instead of cooking flat. The result should finish with about 100 ml of thick, spoon-coating broth, not a watery soup.

Ingredients
| Ingredient | US | Metric | Substitute / note |
|---|---|---|---|
| Cooked pork intestines | 4.2 oz | 120 g | Ready-cooked from a Chinese deli, or home-cooked and thoroughly cleaned — see the steps (adaptation). |
| Cooked pork lung | 2.8 oz | 80 g | Same sourcing as the intestines; omit and add extra intestine if lung is unavailable (adaptation). |
| Huoshao baked wheat buns | 2 buns, about 100 g | 2 buns, about 100 g | Plain baked buns from a Chinese bakery; thick flour flatbread is a substitute (adaptation). |
| Pork-bone stock (old stock substitute) | 1¼ cups | 300 ml | The report's old stock simmers 4 hours; a good store-bought pork or chicken stock is the home substitute (adaptation). |
| Garlic, minced | 0.5 oz | 15 g | — |
| Chilli oil | 2 tsp | 10 ml | — |
| Fermented bean curd, mashed | 1 tsp | 5 g | — |
| Soy sauce | 2 tsp | 10 ml | — |
| Salt | ½ tsp | 3 g | Adjust to taste — the stock's saltiness varies. |
| Star anise, cinnamon, scallion, ginger | 1 g each | 1 g each | For the broth; a pinch each at home. |
| Flour and vinegar, for cleaning raw offal | 50 g flour + 20 ml vinegar | 50 g flour + 20 ml vinegar | Only if cleaning raw intestines at home; skip if using ready-cooked offal. |
Equipment
- Clay pot or heavy saucepan with a lid
- Ladle
- Small bowl for the finishing seasonings
Steps
- Clean raw offal — only if starting raw. Rub 1 kg fresh intestines with 150 g flour and 60 ml vinegar for 10 minutes, rinse three times, and repeat once (about 20 minutes total) until the walls are white, odour-free and not slimy. Rinse lung pieces (3 cm cubes) from the windpipe three times, then blanch 5 minutes with cooking wine. Skip this whole step if using ready-cooked offal.
- Make or heat the broth. For the report's old stock, simmer 5 kg pork bones in 20 litres of water with 50 g star anise, 30 g cinnamon, 200 g scallion and ginger, 500 ml soy sauce and 100 g salt: boil 30 minutes, then simmer 4 hours and strain. At home, heat 300 ml good stock with a pinch of star anise, cinnamon, scallion and ginger instead.
- Stew the offal and buns. Pour the stock into a clay pot or heavy pan over medium heat. Add the cooked intestines and lung and simmer 2 minutes. Halve the buns, add them, and simmer on low heat for 15 minutes, until the buns have absorbed the broth but still hold their shape and about 100 ml of thick broth remains.
- Finish and serve. In the last 2 minutes, stir in the garlic, chilli oil, fermented bean curd, soy sauce and salt, and keep at a gentle simmer until just bubbling. The offal centre must reach at least 75 °C / 167 °F and hold for at least 3 minutes. Serve in a bowl, with the buns soaked through and the broth spoon-coating.

Technique: low simmer for the buns, last minutes for the sharpness
The buns are the failure point: a rolling boil shreds them into porridge, while too short a simmer leaves them dry inside. Fifteen minutes on low heat is the balance, and the broth should reduce to roughly a third of its starting volume, thick enough to coat a spoon. Keep the salt at 1.5–2% of the broth if you can measure it; the bean curd and soy both add salt, so season the broth lightly first and correct at the end.
Variations
- Intestine only: use 200 g cooked intestine and skip the lung (adaptation).
- Milder: halve the chilli oil and garlic; the broth still carries the dish (adaptation).
Frequently asked questions
Where do I buy cooked intestines and huoshao buns?
From a Chinese deli or bakery; ready-cooked offal is the sensible home route, since cleaning raw intestines takes about twenty minutes and a strong stomach.
Why did my buns fall apart?
The broth was boiling, or they simmered longer than fifteen minutes. Keep it at a low simmer and watch the clock.
Can I use chicken stock?
Yes — it will be lighter than pork-bone stock but still works; the report's old stock is pork-based.
Storage and freezing
Best eaten fresh from the pot. Leftovers keep 1 day refrigerated; reheat gently to a full simmer, but expect the buns to soften further. Do not freeze the finished dish.

Source note: ingredients, quantities and steps are adapted from the original ClouChef R&D report for 卤煮火烧 (data/reports/87.md). The report's pricing, margin and marketing sections are deliberately omitted here; no B2B cost is presented as a home-cook cost. The report's own cost table is arithmetically wrong — it prices a batch of reusable old stock as a single-serving cost, so its total contradicts its own note on the stock's real per-serving cost — so no cost figures are reproduced. The ready-cooked offal shortcut, the stock substitute and the bun substitute are adaptations and are labelled as such. Original poster image: clouchef.com (卤煮火烧_87.jpeg).
