Century egg with mashed peppers (皮蛋擂辣椒, pí dàn léi lā jiāo) is a rustic Hunan cold dish that proves the power of simple ingredients. Green peppers are roasted or pan-fried until their skins are blistered and charred, then mashed in a mortar with century eggs (pidan), garlic, salt, and a splash of soy sauce. The result is a chunky, creamy, spicy mixture that looks unpretentious but delivers an explosion of flavor. The roasted peppers are smoky and sweet, the century egg is rich and creamy with its characteristic mineral tang, and the garlic adds a sharp bite. The name 'lei' means to pound or mash in a mortar, which is the traditional preparation method. This dish is a summertime favorite in Hunan, served cold with congee or rice, and it exemplifies the Hunan philosophy of making extraordinary food from ordinary ingredients.
The word 'lei' (擂) in the dish name refers to the traditional method of pounding ingredients in a mortar and pestle. In Hunan, the mortar (lei cha guan) is an essential kitchen tool, used not only for this dish but also for making lei cha (pounded tea), a traditional Hakka beverage. The pounding process does more than just combine ingredients; it breaks down cell walls and releases essential oils and juices that chopping cannot achieve. The result is a deeper, more integrated flavor. Century eggs (pidan) are another ingredient with deep cultural roots. They are made by preserving duck, chicken, or quail eggs in a mixture of clay, ash, salt, quicklime, and rice hulls for several weeks to months. The alkaline preservation process transforms the egg white into a dark, translucent jelly and the yolk into a creamy, dark green substance with a complex, mineral flavor. Despite the name, century eggs are not actually preserved for a hundred years; the name is a Western mistranslation. In Chinese, they are called songhua dan (pine-patterned eggs) for the delicate, pine-branch-like patterns that appear in the preserved egg white.

Ingredients
Century eggs are available at Chinese supermarkets. Long green chilies or jalapenos work well for this recipe.
- 3 century eggs (pidan), peeled
- 6-8 green peppers (long green chilies or jalapenos)
- 4 garlic cloves
- 1 tbsp light soy sauce
- 1 tsp sesame oil
- 1/2 tsp salt
- 1 tsp sugar
- 1 tsp black vinegar
- 1 tbsp cooking oil
- 1 scallion, chopped for garnish
Step-by-Step Instructions
- Roast the peppers. Heat a dry cast-iron skillet or wok over medium-high heat. Place the whole green peppers in the dry pan, pressing them down with a spatula. Cook for 2 to 3 minutes per side until the skin is blistered, charred in spots, and the peppers are softened. Turn occasionally to char all sides evenly. The charring is what gives the dish its smoky flavor. Alternatively, you can roast the peppers over an open flame on a gas stove, turning with tongs until evenly charred. Once charred, transfer to a bowl and cover with plastic wrap for 5 minutes to steam, which loosens the skins. Peel off most of the charred skin, leaving some for flavor.
- Prepare the century eggs. Peel the century eggs. Rinse them under cold water to remove any shell fragments. Cut each egg into quarters or rough chunks. Century eggs have a translucent, amber-colored egg white and a creamy, dark green-gray yolk. The yolk is rich and creamy, while the white is gelatinous and slightly tangy. The unique flavor comes from the curing process, which uses alkaline materials to transform the egg over weeks or months. Set the chopped eggs aside.
- Mash the garlic and peppers. Place the garlic cloves and a pinch of salt in a mortar. Pound with the pestle until the garlic is crushed into a rough paste. Add the roasted, peeled peppers and continue pounding until they are broken down into a chunky paste. The peppers should not be completely smooth; some texture is desirable. The pounding (lei) is what releases the peppers' full flavor and combines it with the garlic. If you do not have a mortar and pestle, you can roughly chop everything very finely on a cutting board, though the texture will be different.
- Combine with century egg. Add the chopped century egg pieces to the mortar. Gently pound and fold to combine, breaking the egg into smaller chunks but not completely mashing it. The creamy yolk will blend with the pepper paste, creating a marbled appearance. Add the light soy sauce, sesame oil, sugar, black vinegar, and salt. Mix well. Taste and adjust seasoning. The flavor should be spicy, savory, slightly tangy from the vinegar, and rich from the century egg yolk.
- Chill and serve. Transfer the mixture to a serving dish. For the best flavor, refrigerate for 30 minutes to allow the flavors to meld. The dish is traditionally served cold or at room temperature. Garnish with chopped scallions just before serving. Serve with steamed rice or plain congee. The contrast between the cold, spicy, creamy mixture and hot rice or congee is perfect. This dish also makes an excellent topping for cold noodles or tofu. In Hunan, it is a beloved summer dish, as the spicy peppers induce sweating, which is believed to cool the body.
- Char the peppers well. The blistering is what gives the dish its signature smoky flavor.
- Use a mortar and pestle. Pounding releases flavors that chopping cannot achieve.
- Choose the right peppers. Long green chilies or jalapenos provide the best balance of heat and flavor.
- Let it chill. Resting in the refrigerator for 30 minutes allows the flavors to meld beautifully.

Frequently Asked Questions
- Overcooking the main ingredient — Hunan steamed dishes rely on freshness; steam just until cooked through.
- Skipping the fermented chilies — duojiao is what makes the dish authentically Hunan, not just spicy.
- Using cold water in the steaming liquid — always start with hot water to maintain consistent steam temperature.
Steamed white rice is essential — the savory juices from the steaming process are meant to be mixed with rice. Add a simple stir-fried green vegetable like Hunan stir-fried spinach or garlic bok choy for a complete meal. A bowl of clear soup on the side helps balance the bold flavors.
What Makes It Hunan
Century Egg with Mashed Peppers is a quintessential Hunan dish that showcases the bold, unapologetic flavors of Xiang cuisine. Unlike Sichuan's numbing-spicy heat, Hunan cooking relies on dry, direct spiciness from fresh and dried chilies, complemented by the deep umami of fermented ingredients like duojiao (chopped salted chilies) and douchi (fermented black beans).
The hallmarks of Xiang cuisine — dry chili heat, bright acidic tang, and the deep umami of smoke and fermentation — come together in this dish. There is no numbing distraction of Sichuan peppercorn to mask the ingredients; the spice here is meant to be felt and savored.
Whatever the technique, the goal is the same: clean, layered flavors with a clear throughline of chili heat and the savory depth that only slow building — through fermentation, smoking, or patient braising — can produce.
This recipe represents the Hunan preparation. Many Chinese-American restaurant versions of Hunan dishes add extra sugar, use pre-made sauces, or deep-fry ingredients that are traditionally stir-fried. The key difference is that Hunan cooking uses fresh whole chilies, fermented condiments like duojiao and douchi, and high-heat wok techniques — not thick, sweet sauces.
