What Is Dried Fish (Huo Bai Yu)?
Huo Bai Yu (火焙鱼, fire-roasted fish) are small freshwater fish, typically less than 10cm long, caught from the Dongting Lake region in northern Hunan. The fish are cleaned, lightly salted, and then slowly roasted over a wood or rice husk fire until semi-dried. This fire-roasting process (焙, bei) gives the fish their name and distinctive smoky flavor. Unlike fully dried fish, Huo Bai Yu retain some moisture, giving them a tender yet chewy texture. The combination of lake fish, salt, and smoke creates a concentrated umami flavor that is uniquely Hunan.
Flavor Profile
Smoky, savory, and intensely umami with a satisfying chewy texture. The fire-roasting gives a distinctive smoky aroma, while the natural oils of the fish concentrate during drying. The flavor is deeper and more complex than regular dried fish, with a hint of sweetness from the fresh water fish.
Role in Hunan Cuisine
Huo Bai Yu is a celebrated ingredient in Hunan's Dongting Lake cuisine. The most iconic preparation is huo bai yu chao lajiao (fire-roasted fish stir-fried with chilies), where the fish are pan-fried with dried red chilies, garlic, ginger, and perilla leaves. The smoky fish and spicy chilies create a flavor combination that is distinctly Hunan. The fish are also used in steamed dishes with larou (cured pork), added to rice noodle soups for depth, and served as a drinking snack (xiacao) with cold beer. In rural Hunan, families traditionally make their own Huo Bai Yu during autumn when small fish are abundant.
Types & Varieties
Dried fish in Hunan cuisine comes in several distinct varieties, each with its own character. The most celebrated is Huo Bai Yu (火焙鱼), the fire-roasted small fish from the Dongting Lake region. These are typically 3-7cm long, semi-dried, and characterized by their smoky aroma from wood-fire roasting. A second variety is晒鱼 (shai yu, sun-dried fish), which are larger fish split open and dried in the sun without smoke; these have a cleaner, purely fishy flavor without the smoky depth. A third type is咸鱼 (xian yu, salt-cured dried fish), which are heavily salted before drying and have a saltier, more pungent profile. Within the Huo Bai Yu category, there are further distinctions based on the fish species used:银鱼 (yin yu, silver fish) are tiny, translucent fish that are delicately roasted and prized for their tender texture;游鱼 (you yu, small lake fish) are slightly larger and have a meatier bite. The wood used for roasting also creates variety: rice husk produces a milder smoke, while pine wood gives a more assertive smoky character. Some specialty producers use茶籽壳 (tea seed husks), which impart a subtle nutty aroma to the fish.
How It's Made
The traditional production of Huo Bai Yu follows a time-honored process that has been practiced around Dongting Lake for centuries. Small freshwater fish are caught in nets from the shallow waters of the lake, particularly during autumn when the fish are plump and abundant. The fish are immediately cleaned — scaled, gutted, and rinsed in lake water. They are then lightly salted with coarse sea salt, using roughly 3-5% salt by weight, and left to marinate for 2-4 hours. The salting draws out moisture and firms the flesh. Next comes the defining step: the fish are arranged on bamboo screens and placed over a slow-burning fire fueled by rice husks, wood shavings, or tea seed husks. The fish are roasted at a low temperature (60-80°C) for several hours, during which the smoke penetrates the flesh and the fish lose about 40-50% of their moisture. The result is a semi-dried product that is golden-brown on the outside, still slightly pliable, and intensely aromatic. The entire process takes 6-12 hours depending on the size of the fish and the heat of the fire. Traditionally, families around Dongting Lake would make large batches in autumn, storing the fish in cloth bags hung from the rafters.
Nutrition & Health
Huo Bai Yu is a concentrated source of nutrition. The drying process removes water while retaining and intensifying the protein content — dried fish can contain 50-60% protein by weight, making it one of the most protein-dense foods in the Hunan pantry. The fish are rich in calcium and phosphorus, particularly because small fish are eaten whole with bones, providing a bioavailable calcium source. They also contain significant amounts of vitamin D, B vitamins (especially B12), and omega-3 fatty acids, though the levels of omega-3s are somewhat reduced by the roasting process. The smoke curing introduces trace amounts of polycyclic aromatic hydrocarbons (PAHs), which is a consideration for those consuming large quantities regularly. In traditional Chinese medicine, fire-roasted fish is considered warming (yang) in nature, believed to strengthen the spleen and stomach and to dispel dampness from the body. The umami compounds (inosinic acid and glutamic acid) concentrated during drying make Huo Bai Yu a natural flavor enhancer, similar to dried scallops or dried shrimp in this regard.

Frequently Asked Questions
What is the difference between Huo Bai Yu and regular dried fish?
Huo Bai Yu (火焙鱼) is specifically fire-roasted, meaning the fish are slowly smoked over a wood or rice husk fire. Regular dried fish is simply sun-dried or air-dried without any smoke exposure. The fire-roasting gives Huo Bai Yu their characteristic smoky aroma and golden-brown color, while regular dried fish has a paler appearance and a purely fishy flavor without smoky depth.
Do I need to soak dried fish before cooking?
Yes. Rinse the fish briefly under running water, then soak in warm water for 10-15 minutes before cooking. This rehydrates the fish slightly, makes them more tender, and removes excess surface salt. Do not soak for too long, or the fish will lose their smoky flavor. If the fish are very salty, change the soaking water once.
Can I eat dried fish as a snack?
Yes, Huo Bai Yu can be eaten as a drinking snack (xiacao). They are typically pan-fried with a little oil, dried chilies, and perilla leaves, then served cold with beer. The smoky, chewy texture and concentrated flavor make them an excellent bar snack, similar to dried squid or jerky.
How do I remove the fishy smell from dried fish?
The smoky character of Huo Bai Yu already masks much of the fishy smell. To further reduce any fishiness, soak the fish in water with a splash of cooking wine or a few slices of ginger for 15 minutes before cooking. Stir-frying with ginger, scallions, and cooking wine also neutralizes any residual fishy odors during cooking.
What can I substitute for Huo Bai Yu?
Dried small fish (ikan bilis) from Southeast Asian cuisine can substitute, though they lack the smoky character. Add a few drops of liquid smoke during cooking to approximate the fire-roasted quality. Dried shrimp can also work in a pinch, though the flavor profile is quite different. For the closest match, look for smoked dried fish from other Chinese lake regions.
Are the bones in dried fish safe to eat?
Yes. The fish used for Huo Bai Yu are small (3-7cm), and their bones become brittle during the roasting and drying process. When pan-fried or stir-fried, the bones soften further and are safe to eat whole. This is actually beneficial, as the bones provide calcium. However, very small children should be monitored.
How to Choose
Look for fish that are uniform in size (3-7cm), golden-brown in color, and semi-dry (not brittle). The fish should have a smoky aroma without any rancid or ammonia smell. Avoid fish that are too dark (over-smoked) or too pale (under-roasted). Authentic Dongting Lake Huo Bai Yu are sold in Hunan specialty shops and some Chinese grocery stores. When buying, check that the fish are whole and not broken into fragments.
How to Store
Store in an airtight container or sealed plastic bag in a cool, dry place for up to 3 months. For longer storage, keep in the refrigerator for up to 6 months or freezer for 1 year. Before using, rinse briefly and soak in warm water for 10-15 minutes to rehydrate slightly. This makes the fish more tender and removes excess salt.

Pairing Guide
Huo Bai Yu pairs perfectly with dried red chilies, perilla leaves (zisu), garlic, and ginger. It complements larou (cured pork) in steamed dishes. The smoky flavor works well with rice wine and soy sauce in stir-fries. It is also excellent with rice noodles and congee, where its concentrated flavor seasons the entire dish.
