Chai Sui Roast Pork: A Taste of Cantonese Nostalgia

The scent of Chai Sui Roast Pork instantly transports me back to childhood. It wasn’t a frequent indulgence, but whenever my family ordered Cantonese takeout, that distinctively sweet and savory aroma wafted from the carton of chow mein, promising a treasure hunt for those ruby-red slices of pork. Those little morsels, sticky and intensely flavored, were always the highlight of the meal, and I’d savor each bite, wishing I could recreate the magic at home. Now, decades later, I finally can – and I’m excited to share this surprisingly simple recipe with you.

Recipe Overview

• Prep Time: 10 minutes + 1 hour resting
• Cook Time: 15-20 minutes
• Total Time: 1 hour 25-30 minutes
• Servings: 4
• Yield: Approximately 1 pound of roast pork
• Dietary Type: Not Gluten-Free (contains soy sauce and yellow bean paste); Not Dairy-Free

Ingredients

• 1 lb pork tenderloin
• 2 tablespoons rice wine or 2 tablespoons dry sherry
• 3 tablespoons brown sugar
• 3 tablespoons peanut oil
• 1 tablespoon yellow bean paste
• 2 tablespoons dark soy sauce
• 2 tablespoons red fermented tofu

Equipment Needed

• Mixing bowl
• Spoon
• Roasting pan
• Roasting rack

Instructions

1. In a mixing bowl, combine the rice wine (or dry sherry), brown sugar, peanut oil, yellow bean paste, dark soy sauce, and red fermented tofu. Whisk or stir well until the brown sugar is mostly dissolved and the ingredients are thoroughly combined into a smooth sauce.
2. Place the pork tenderloin in the bowl with the sauce. Spoon the sauce liberally over the pork, ensuring it is fully coated. Turn the pork to coat all sides.
3. Let the pork rest in the sauce at room temperature for at least 1 hour. This allows the flavors to penetrate the meat. You can also refrigerate the pork in the marinade for a longer period, even overnight, but allow it to come to room temperature before roasting for even cooking.
4. Preheat your oven to 400°F (200°C). Make sure the oven rack is positioned in the center of the oven.
5. Place a roasting rack inside a roasting pan. This will allow air to circulate around the pork, promoting even cooking and browning.
6. Transfer the marinated pork tenderloin to the roasting rack in the roasting pan.
7. Roast the pork in the preheated oven for 15 to 20 minutes, or until the juices run clear when you pierce the thickest part of the tenderloin with a fork or meat thermometer. The internal temperature should reach 145°F (63°C) for medium doneness.
8. The outside of the pork should be a beautiful golden brown color. If it starts to brown too quickly, you can loosely tent it with foil during the last few minutes of cooking.
9. Once cooked, remove the pork from the oven and let it rest for at least 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
10. Slice the Chai Sui Roast Pork against the grain into thin slices. Serve immediately and enjoy!

Expert Tips & Tricks

• Marinating Time is Key: Don’t skimp on the marinating time. The longer the pork sits in the sauce, the more flavorful and tender it will become.
• Achieving the Perfect Color: The combination of dark soy sauce and brown sugar is responsible for that signature deep red color. For an even deeper color, you can add a tiny drop of red food coloring (optional, but commonly used in commercial preparations).
• Doneness Check: Use a meat thermometer to ensure the pork is cooked to the correct internal temperature. Overcooked pork tenderloin can be dry and tough.
• Crispy Edges: For extra crispy edges, you can broil the pork for the last minute or two of cooking, keeping a close eye to prevent burning.
• Sauce Reduction: After removing the pork, pour the pan drippings into a small saucepan. Simmer over medium heat until the sauce thickens slightly. This can be drizzled over the sliced pork for extra flavor.

Serving & Storage Suggestions

Chai Sui Roast Pork is incredibly versatile. It’s delicious served:

• As part of a Cantonese-style meal with stir-fried vegetables and rice.
• Sliced and added to chow mein or lo mein noodles.
• In steamed buns (bao).

Storage:

Reheating:

• Oven: Reheat sliced pork in a preheated oven at 325°F (160°C) until warmed through. Add a little water or broth to the pan to prevent drying.
• Microwave: Reheat sliced pork in the microwave on medium power until warmed through. Be careful not to overheat, as it can become tough.
• Stovetop: Reheat sliced pork in a skillet over medium heat with a little oil or broth.

• Other Cuts of Pork: While pork tenderloin is ideal for its tenderness, you can also use pork loin or pork shoulder (although cooking times will need to be adjusted accordingly).

FAQs (Frequently Asked Questions):

Q: Can I make this recipe ahead of time?
A: Yes! The pork can marinate in the refrigerator for up to 24 hours. You can also roast the pork ahead of time and slice it just before serving.

Q: Where can I find red fermented tofu?
A: Red fermented tofu can be found in Asian grocery stores, typically in jars or vacuum-sealed packages. It has a strong, pungent flavor, so a little goes a long way.

Q: How do I know when the pork is cooked through?
A: The best way is to use a meat thermometer. Insert it into the thickest part of the pork and ensure it reaches an internal temperature of 145°F (63°C). The juices should also run clear when you pierce the pork with a fork.
