Century egg with houttuynia (皮蛋拌折耳根, pí dàn bàn zhé ěr gēn) is a bold, polarizing Hunan cold dish that pairs two of China's most distinctive ingredients. Creamy, gelatinous century eggs (preserved eggs) are combined with fresh houttuynia leaves — also called 'fish mint' for their raw, fishy, peppery aroma — and dressed with chili oil, garlic, and black vinegar. The result is a clash of strong flavors and textures: the rich, mineral creaminess of the egg against the bright, pungent, almost coriander-like bite of the greens. It is a dish that locals adore and newcomers find challenging — a true test of adventurous eating. For those who love bold, herbaceous, funky flavors, it is an unforgettable Hunan classic, especially beloved in the Xiangxi mountain region.
Houttuynia (折耳根, zhé ěr gēn, also called 'fish mint') is a leafy herb with arrow-shaped leaves and a powerful, divisive aroma — variously described as fishy, peppery, citrusy, and metallic. It grows wild across the mountains of southwest China and is a defining ingredient in Guizhou, Sichuan, and western Hunan (Xiangxi) cooking. People either love it or hate it; there is little middle ground. In Xiangxi, houttuynia is eaten fresh in salads, stirred into dipping sauces, and paired with strong flavors like century egg that can stand up to it. The combination reflects a regional palate that prizes pungent, herbal, bold flavors over subtlety. To locals, the first taste of houttuynia in spring is a sensory homecoming — the flavor of the mountains themselves.

In Century Egg with Houttuynia, cold dishes showcase raw chili heat and vinegar brightness, served as appetizers that awaken the palate before the main feast. What sets it apart is the layering of the preserved vegetables that add umami and saltiness, the dark vinegar that provides the sour counterpoint essential to Hunan flavor balance, and the chili oil that is drizzled generously over nearly everything in Hunan. For Hunan families, dishes like this are daily fare — a testament to the region's belief that every meal should be vibrant and memorable.
Ingredients
Fresh houttuynia is sold at Asian markets, often labeled 'fish mint' or 'zhe er gen'. Century eggs (preserved eggs) are available in most Asian grocery stores.
- 3 century eggs (preserved eggs)
- 150 g fresh houttuynia (fish mint) leaves and tender stems
- 3 garlic cloves, minced
- 1 tbsp ginger, minced
- 2 tbsp chili oil (with sediment)
- 1 tbsp light soy sauce
- 1 tbsp black vinegar
- 1 tsp sugar
- 1/2 tsp salt
- 1 tsp sesame oil
- 1 fresh red chili, minced (optional)
- 1 scallion, green for garnish
Step-by-Step Instructions
- Prep the houttuynia. Wash the houttuynia thoroughly in several changes of cold water — it grows in damp soil and holds grit. Pick the leaves and tender stem tips, discarding any tough or yellowed stems. Drain well and pat dry. If the leaves are very long, cut them into 5 cm pieces. Some cooks prefer to blanch the houttuynia for 10 seconds to soften the pungency, but traditionally it is eaten raw to preserve its bright, peppery aroma. Taste a leaf first — if it is overwhelmingly strong, a brief blanch will mellow it.
- Prep the century eggs. Shell the century eggs and rinse them gently. Cut each egg into 6 to 8 wedges — the yolk will be soft and dark, the white translucent amber jelly. Handle them gently so the soft yolk does not smear. Arrange the wedges in a shallow serving dish. If the eggs are very soft, chill them in the fridge for 30 minutes first — cold eggs slice more cleanly. The contrast of the dark yolk and jelly-like white is part of the dish's visual appeal.
- Mix the dressing. In a small bowl, combine the minced garlic, ginger, chili oil, light soy sauce, black vinegar, sugar, salt, sesame oil, and minced fresh chili if using. Stir until the sugar dissolves. Taste and adjust — the dressing should be salty, tangy, spicy, and slightly sweet, with a strong garlic kick. The vinegar and sugar are important to balance both the rich egg and the pungent greens. This bold dressing is what unites the two strong ingredients.
- Assemble the dish. Scatter the houttuynia leaves over and around the century egg wedges. Pour the dressing evenly over the top, making sure both the eggs and the greens get a good coating. Let it sit for 5 minutes so the flavors mingle and the greens soften slightly in the dressing. The dish can be served at room temperature or chilled — chilling makes it more refreshing, especially in summer.
- Garnish and serve. Scatter the scallion greens over the top for a fresh, bright contrast. Serve as a cold appetizer or side dish, with rice or on its own as a drinking snack. To eat, take a piece of century egg with some houttuynia and dressing together — the creamy, mineral egg and the pungent, peppery greens are meant to be eaten in one bite. Be prepared for a flavor explosion: it is funky, creamy, herbal, and spicy all at once. Adventurous eaters will fall in love; the cautious may need a few tries.
- Wash houttuynia thoroughly. It holds grit from damp soil — wash in several changes of water.
- Chill century eggs before slicing. Cold eggs cut cleanly; warm yolks smear.
- Balance the dressing boldly. Strong vinegar, garlic, and chili are needed to stand up to two pungent ingredients.
- Let it rest 5 minutes. A brief rest lets the greens soften and the flavors mingle.
Variations
Like most Hunan home cooking, this dish welcomes small adjustments to suit your taste and pantry.
With tofu
Add cubes of soft tofu for a milder, creamier version that tempers the strong flavors — a popular compromise for newcomers.
Blanched houttuynia
Briefly blanch the greens for 10 seconds if the raw pungency is too intense — it tames the aroma while keeping the peppery bite.

Frequently Asked Questions
- Wok not hot enough — the oil should be shimmering but not smoking before you add ingredients.
- Overcrowding the wok — cook in batches if needed; too much food at once causes steaming instead of stir-frying.
- Cutting ingredients unevenly — uniform pieces ensure everything cooks at the same rate.
- Adding sauce too early — let the ingredients sear first, then add sauce in the final 30 seconds.
Serve immediately with steamed white rice — the dish should still be sizzling when it reaches the table. A simple soup like egg drop soup or tomato egg soup provides a cooling contrast. For a full Hunan spread, add one cold appetizer and one vegetable dish.
What Makes It Hunan
Century Egg with Houttuynia 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.
