There's a dish in Chinese restaurants that turns heads the moment it lands on the table: a whole fish head, split open like a book, blanketed in a mosaic of green and red chilies, glistening with oil and steaming with an aroma that makes everyone at the table lean in. It's called 剁椒鱼头 (Duò Jiāo Yú Tóu), or Chopped Chili Fish Head, and it's one of the most iconic dishes in Hunan cuisine.

The problem? Making it from scratch requires chopping fresh chilies, fermenting them for days and building a complex sauce base. That's a project, not a weeknight dinner.

The solution is Chuan Wa Zi Double Pepper Chili Sauce (川娃子雙椒醬). This dual-chili relish already contains the green-and-red chili blend, aromatics and oil, giving you a shortcut that does not taste like a shortcut.

Here's everything you need to know about this dish, why the sauce works and how to make it at home.

The dish: a Hunan classic with a double-chili twist

Chopped Chili Fish Head is one of the signature dishes of Hunan cuisine, a cooking tradition known for bold, fresh and fiery flavors. Unlike Sichuan cuisine, which leans on numbing peppercorns and dried chilies, Hunan cooking favors fresh chilies, fermented chilies and clean, direct heat.

The dish traditionally features a bighead carp (鳙鱼), a freshwater fish prized for its large, gelatinous head and tender meat. The head is split open, steamed with fermented chopped chilies and finished with hot oil and scallions.

The double pepper version (双椒) uses both green and red chilies, combining the freshness and brightness of green peppers with the warmer, aromatic heat of red peppers. It is colorful, layered and made for sharing.

Why Chuan Wa Zi Double Pepper Chili Sauce works

The active product is a 230g jar of Chinese double pepper chili sauce made with two chili varieties for a more complex, rounded heat profile. It works especially well here for three reasons:

It already has the double-chili blend. Instead of sourcing, chopping and fermenting two types of chilies, you can spoon the prepared sauce over the fish.

It brings savory depth. The sauce is designed as both a cooking ingredient and table condiment, so it contributes chili flavor, color and umami to the fish and its juices.

It delivers fresh-spicy flavor. The green and red chili combination gives the dish layered heat rather than a flat blast of spice.

In Chinese food culture, “下饭” (xià fàn) means “makes rice go down.” The savory, spicy sauce pooling at the bottom of the plate is built for spooning over steamed rice.

The recipe: Double Pepper Fish Head with Chuan Wa Zi

Prep time: 15 minutes
Cook time: 15 minutes
Total time: 30 minutes
Serves: 3–4 people

Ingredients

For the fish head:

• 1 large fish head, about 2–3 lbs. Bighead carp is traditional, but salmon head, sea bass head, tilapia or snapper can work.
• 1 tablespoon Shaoxing wine, or dry sherry
• 1 teaspoon salt
• ½ teaspoon white pepper
• 4–5 slices fresh ginger
• 2 scallions, cut into 2-inch lengths

For the sauce blanket:

• 5–6 tablespoons Chuan Wa Zi Double Pepper Chili Sauce
• 3 cloves garlic, minced
• 1 tablespoon fresh ginger, minced
• 1 tablespoon soy sauce
• 1 teaspoon sugar
• 2 tablespoons chicken stock or water

For the finish:

• 3 tablespoons neutral oil, for the hot oil pour
• 2 scallions, thinly sliced, green parts only
• 1 teaspoon sesame oil

For serving:

• Steamed jasmine rice or thin egg noodles
• Extra Chuan Wa Zi Double Pepper Chili Sauce on the side

Instructions

1. Prep the fish head. Ask your fishmonger to split the head in half lengthwise but keep it attached at the back. Rinse thoroughly under cold water, remove the gills, scrape away any dark blood along the spine and check for scales. Pat dry.

2. Marinate the fish. Rub the fish head with Shaoxing wine, salt and white pepper. Tuck the ginger slices and scallion lengths underneath and inside the head. Let it sit for 15 minutes.

3. Build the sauce blanket. Combine the Chuan Wa Zi Double Pepper Chili Sauce, minced garlic, minced ginger, soy sauce, sugar and chicken stock or water. Stir until well mixed. The sauce should be savory, spicy and slightly sweet.

4. Set up your steamer. Fill a large wok or steamer pot with 2 inches of water and bring it to a rolling boil. Place a steaming rack inside.

5. Arrange the fish head. Place it skin-side up and opened flat on a heatproof, rimmed plate that fits inside the steamer.

6. Blanket the fish with sauce. Spoon the Chuan Wa Zi mixture evenly over the fish head, covering it from edge to edge. Let some sauce and oil settle into the crevices.

7. Steam. Cover and steam over high heat for 12–15 minutes for a 2–3 lb head, or 15–18 minutes for a larger head. The meat is ready when opaque and easily flaked at the thickest point. Do not overcook.

8. Finish with hot oil. Remove the plate carefully and scatter sliced scallions over the top. Heat the neutral oil until shimmering and just beginning to smoke. Pour it directly over the scallions and sauce, then finish with sesame oil.

9. Serve immediately. Bring the steaming plate to the table with jasmine rice or thin egg noodles. Offer extra Chuan Wa Zi Double Pepper Chili Sauce on the side.

Pro tips for the best Double Pepper Fish Head

Choose the right fish head. Bighead carp is traditional because the head is large, meaty and gelatinous. Salmon head is a richer substitute, while sea bass or tilapia create a leaner version.

Ask your fishmonger to split it. Splitting a fish head at home is messy and requires a heavy cleaver. Many Asian markets can do it for you.

Do not skip the marinade. Shaoxing wine, salt and white pepper season the meat and help reduce fishiness.

Watch the water level. Steaming at high heat evaporates water quickly. Start with at least 2 inches and do not let the pot run dry.

Do not overcook. Start checking at the 12-minute mark and remove the fish as soon as the meat flakes.

Keep the hot-oil finish. Pouring hot oil over the scallions and sauce blooms the aromatics and creates the glossy finish.

Save the juices. The sauce and fish juices at the bottom of the plate are perfect for spooning over rice.

Variations to try

Hunan-style: Add 1 tablespoon fermented black beans, or douchi, for a deeper flavor.

Citrus twist: Add 1 teaspoon grated lime or kumquat zest for a bright lift.

Extra garlic: Double the garlic. The hot-oil pour will mellow its raw bite.

Extra heat: Add a teaspoon of Chuan Wa Zi Chili Oil Sauce or a pinch of crushed dried chilies.

Fish head with tofu: Arrange thick slices of soft tofu around the fish head before steaming so they absorb the sauce.

Noodle base: Serve the fish head over cooked thin egg noodles instead of rice.

What to serve with Double Pepper Fish Head

Steamed jasmine rice: The classic pairing, perfect for soaking up the savory spicy oil.

Blanched greens: Bok choy, gai lan or spinach with soy sauce and sesame oil provide a clean contrast.

Cold cucumber salad: Smashed cucumbers with garlic and black vinegar balance the heat.

Cold beer or iced tea: A crisp lager or iced jasmine tea cuts through the richness and spice.

Who should make this dish?

Anyone hosting a dinner party: A steaming whole fish head is a showstopper that looks far more complicated than it is.
