Growing up, this dish was the absolute centerpiece of the Chinese New Year dinner table. It was the kind of grand, festive dish that was strictly reserved for entertaining guests or celebrating at weddings. Over the years, I’ve seen many home cooks struggle with making it, often complaining that the pork skin turns out too tough to even slice. After consulting with my sister-in-law, who cooks in the traditional Zhuji style, I realized most recipes skip a crucial secret step: the “Wu” (捂) or pre-braising method.
By taking the time to slowly simmer the pork before steaming it, you guarantee that every single bite is luxuriously tender. It takes a bit of time, but the reward is a restaurant-quality dish right in your home kitchen.
What Is Mei Gan Cai Kou Rou?
Mei Gan Cai Kou Rou (梅菜扣肉) is a classic Chinese banquet dish consisting of thick slices of pork belly steamed upside down over a bed of savory, sweet, and umami-rich preserved mustard greens (Mei Gan Cai). The greens absorb the rich fat from the pork, creating an incredible balance of flavors.

Ingredients
For the Pork and Blanching:
- 2 lbs (900g) square piece of Pork Belly (skin-on)
- 5 slices fresh ginger
- 5 sections scallion (white parts)
- 2 tbsp Shaoxing Wine
- 2 tbsp Dark Soy Sauce (for coloring the skin)
For the “Wu” (Pre-Braise) Liquid:
- 4 slices fresh ginger
- 4 sections scallion (white parts)
- 2 bay leaves
- 1 cinnamon stick
- 2 dried chili peppers
- 2 whole star anise
- 1 piece dried tangerine peel (chenpi)
- 2 tbsp Dark Soy Sauce
- 2 tbsp Light Soy Sauce
- 2 tbsp Shaoxing Wine
- 1 tbsp Oyster Sauce
- 1 tbsp sugar
- 1 tsp salt
- Water (enough to cover the pork)
For the Steaming Sauce (per bowl/portion):
- 2 tbsp reserved braising liquid (from the step above)
- 2 tbsp Light Soy Sauce
- 1 tbsp Oyster Sauce
- 1 tbsp Shaoxing Wine
- 1 tbsp Dark Soy Sauce
- 1 tbsp sugar
For the Mei Gan Cai (Preserved Mustard Greens):
- 7 oz (200g) Mei Gan Cai
- 6 cloves garlic, minced
- 1 tbsp sugar
- 1 tbsp Oyster Sauce
Equipment Needed
- Deep Wok or Frying Pan with a TIGHT-FITTING LID: Crucial for safety during the frying step.
- Large Steamer: Capable of holding a deep heat-proof bowl.
Prep & Mise en Place
- Rinse the Greens: Mei Gan Cai can be very salty and sandy. Rinse it thoroughly under cold water. If it’s extremely salty, soak it for 15 minutes, then squeeze out all excess moisture and chop it into smaller pieces.
- Dry the Pork: After blanching the pork and coating it in soy sauce, use a hair dryer or paper towels to ensure the skin is completely dry before frying. Moisture hitting hot oil will cause violent splattering.
Cooking Process
1. Blanch the Pork (4 minutes) Place the pork belly in a pot of cold water with 5 slices of ginger, 5 scallions, and 2 tbsp Shaoxing wine. Bring to a boil and cook for 2 minutes skin-side up, then flip and cook for 2 minutes skin-side down. Remove, rinse with warm water, and pat completely dry.
2. Color the Skin (10 minutes) Rub the 2 tbsp of dark soy sauce all over the pork. Place it skin-side down in a shallow dish with the leftover dark soy sauce to soak for 10 minutes. Remove and dry the skin completely.
3. Deep Fry the Skin (3-5 minutes at 350°F/175°C) — ⚠️ SAFETY WARNING Heat about 1/2 inch of oil in a wok. Once hot, carefully lower the pork into the oil, skin-side down, and immediately cover the pot with a lid. The popping will be loud and violent. Fry for about 3-5 minutes until you smell a slight toasty aroma. Turn off the heat and wait until the oil stops popping before opening the lid. The skin should be blistered and dark red.
💡 Why We Blister the Skin: Frying triggers the Maillard reaction, creating a deep, complex flavor. More importantly, blistering the skin changes its cellular structure. When it later meets moisture during braising and steaming, those tiny blisters act like sponges, soaking up the savory sauce and resulting in that iconic “tiger skin” texture.
4. The Secret “Wu” (Pre-Braise) (40-50 minutes) Place the fried pork into a clean pot. Add the ginger, scallions, bay leaves, cinnamon, chilies, star anise, dried tangerine peel, and all the “Wu” braising liquids. Add enough water to just cover the pork. Pierce the pork skin several times with a toothpick to help it absorb flavor. Bring to a boil, then reduce to medium heat and simmer covered for 40 to 50 minutes. Flip halfway through. It is ready when a chopstick can easily pierce the meat. Remove the pork and reserve the liquid.
5. Slice and Sauce Once the pork is cool enough to handle, slice it 1/4 to 1/2-inch (0.5-1cm) thick. Keep the bottom slightly attached if you want to maintain a perfect square shape, or slice all the way through. Mix the Steaming Sauce ingredients together and brush it evenly over every slice. Place the sliced pork, skin-side down, into a heat-proof steaming bowl.
6. Stir-Fry the Mei Gan Cai (3 minutes) Heat a little oil in a wok. Fry the minced garlic until fragrant, then add the squeezed Mei Gan Cai. Stir in 1 tbsp sugar and 1 tbsp oyster sauce (do not add salt). Stir-fry evenly and remove from heat. Pack this mixture tightly on top of the pork in the steaming bowl.
7. Steam to Perfection (1 hour) Cover the bowl with a plate or a tight layer of foil (to prevent condensation from watering down the sauce). Steam over boiling water for 1 hour.
8. Invert and Serve Remove the bowl from the steamer. Place a serving plate upside down over the bowl, and carefully flip them together. Lift the bowl off. If there is excess liquid, pour it into a saucepan, thicken it with a little cornstarch slurry, and pour it over the pork for a glossy finish.
Why This Recipe Works
- The “Wu” Technique: Pre-braising the whole block of pork breaks down the tough connective tissues in the skin before slicing, guaranteeing a tender bite.
- Moisture Control: Covering the bowl during the final steaming phase ensures the pure, concentrated flavors of the pork and mustard greens aren’t diluted by water vapor.
- Flavor Balancing: Mei Gan Cai is naturally dry and salty; stir-frying it with a touch of sugar and oyster sauce before steaming allows it to perfectly complement the rich, fatty pork without overpowering it.
Common Mistakes & Troubleshooting
- Mistake: The pork skin is tough and rubbery.
- Cause: You skipped the pre-braising step or didn’t steam it long enough.
- Solution: Ensure you simmer the whole block until a chopstick pierces it easily before you slice and steam it.
- Mistake: The dish is overwhelmingly salty.
- Cause: The Mei Gan Cai wasn’t washed properly, or extra salt was added to the vegetable stir-fry.
- Solution: Always taste a tiny piece of your preserved greens after washing. If it’s too salty, soak it in fresh water for 15 minutes before squeezing it dry.
Frequently Asked Questions
Can I substitute Mei Gan Cai? While Mei Gan Cai provides the authentic flavor, you can use dried long beans or even Ya Cai, though the flavor profile will shift slightly.
Why did my pork skin explode violently in the oil? Water and hot oil do not mix. If the skin wasn’t dried completely after the soy sauce soak, it will pop. Always use a lid to protect yourself!
Can I make it ahead? Yes! This dish actually tastes better the next day. You can steam it, let it cool, and store the whole bowl in the fridge. Simply re-steam it for 20 minutes before serving.
Is this an authentic recipe? Yes, this utilizes the traditional Zhuji method, which prioritizes softening the meat through a pre-braise before the final assembly.
How to Serve
This rich, savory dish demands a neutral carbohydrate to soak up the amazing sauce. Serve it alongside fluffy white rice or stuff it into Whole Wheat Steamed Buns for a homemade pork burger.
To cut through the richness of the pork, I highly recommend pairing it with a refreshing Smashed Cucumber Salad and a light, comforting Seaweed Egg Drop Soup.
Storage & Reheat
- Fridge: Store leftovers in an airtight container for up to 4 days.
- Freezer: You can freeze the fully cooked, assembled bowl (tightly wrapped) for up to 3 months.
- Reheating: The best way to reheat is to steam it again for 15-20 minutes until heated through. Microwaving works, but steaming preserves the moisture.

About the Author & Recipe Development
Hi, I’m Lin! Growing up in Sichuan with parents who were both chefs, the kitchen has always been my second home. I developed this recipe after years of watching home cooks struggle with tough pork belly. By incorporating my sister-in-law’s Zhuji-style pre-braising technique, I’ve refined this process to ensure your Kou Rou comes out exceptionally tender, melt-in-your-mouth soft, and perfectly balanced every single time.

- To ensure food safety, the USDA recommends cooking whole cuts of pork to a safe minimum internal temperature of 145°F (62.8°C) with a 3-minute rest time. For braised dishes like this, the temperature will far exceed this to break down the collagen. Read more about USDA Safe Minimum Internal Temperatures.
