From caviar to filet mignon, every culture boasts foods that are hailed as luxurious treats. Yet across the globe, there are dishes that most diners would label downright revolting. In this roundup of 10 disgusting delicacies, we dive into the bizarre, the stomach‑turning, and the historically celebrated foods that make even the bravest foodie squirm.
Discover 10 Disgusting Delicacies Around the World
10 Casu Marzu

When you picture cheese, you probably imagine a smooth, buttery slice that melts in your mouth. In Sardinia, however, cheese takes a grotesque turn. Casu marzu, literally “rotten cheese,” is a prized local specialty teeming with live maggots. The cheese begins as a simple pecorino, soaked in brine, smoked, and left to age in cellars. Then, producers deliberately break the rind, inviting flies to lay eggs inside. These flies, known as cheese skippers, deposit countless eggs that hatch into maggots. As the maggots feed and excrete, their enzymes break down the cheese, turning its interior into a sticky, gooey mass packed with wriggling larvae.
Eating casu marzu comes with its own set of hazards. Disturb the cheese, and the maggots can launch themselves up to 15 cm (6 in) toward your face—safety goggles are advisable. The European Union once banned the cheese over hygiene concerns, but the ban was lifted after it was deemed a traditional Sardinian food, exempt from certain regulations.
9 Hakarl

Sharks are already fearsome, but in Iceland they become a national delicacy known as hakarl. This fermented Greenland shark dates back to Viking times. The shark’s flesh is toxic when fresh, so early Icelanders discovered a method to render it safe: they behead the shark, bury it in a shallow pit, and cover it with rocks to press out harmful compounds. Over six to twelve weeks, the meat ferments and rots in the earth. Afterward, it is cut into strips and hung to dry for several more months until a dry, hard crust forms and the putrid smell reaches its peak.
Despite its reputation as a culinary nightmare—Anthony Bourdain called it “the worst thing” he’d ever tasted, and Gordon Ramsay vomited on camera—hakarl remains a staple of the Thorrablot festival, where participants celebrate ancient Icelandic traditions by sampling the pungent fish.
8 Huitlacoche

Mexico’s culinary fame rests on tacos and mole, yet there’s a lesser‑known treasure: huitlacoche, often called “corn smut,” “fungus,” or the “Mexican truffle.” This plant disease creates puffy grey globules on corn kernels that many deem a plague. However, Mexican chefs harvest the fungus, scraping it from infected ears and incorporating it into dishes. Its flavor is described as delicate, slightly smoky, and reminiscent of morels, though its texture—soft, mushy, and gelatinous—makes it an acquired taste.
When cooked, the fungus turns a deep black, resembling squid ink, and can be used in soups, sauces, or served on its own. Adventurous diners seeking an alternative to ordinary mushrooms might swap a portobello for a spoonful of this earthy, fungal delicacy.
7 Kiviak

In Greenland, holiday feasts wouldn’t be complete without kiviak, a fermented dish that could be described as a turbo‑turducken. The process starts with a large seal, whose body is gutted, greased, and then stuffed with hundreds of auks—birds resembling small penguins. Once the seal is packed, it’s sewn shut, coated in grease to keep maggots out, and buried under heavy stones for several months.
When the fermentation period ends, usually near Christmas, the seal is unearthed, the stitches cut, and the auks—bones and all—are consumed. The birds have become soft from the fermentation, and their intestinal fluids, a rancid juice, are often sucked directly or used as a sauce for other foods. Though extreme, the dish arose from practical necessity: during Greenland’s harsh winter, hunting is perilous, and kiviak provides a reliable protein source.
6 Virgin Boy Eggs

Eggs are a universal staple, but in Dongyang, China, a peculiar tradition turns them into a health‑boosting tonic. Known as virgin boy eggs, the process involves boiling chicken eggs in the urine of pre‑teen boys—typically ten years old or younger. Each spring, urine is collected from schoolchildren, often via buckets placed in classrooms or by volunteers carrying empty bottles to gather the fluid.
Once enough urine is amassed, the eggs are submerged and boiled in the liquid, then removed, cracked, peeled, and returned to a simmering bath of the same urine for up to a full day. The resulting eggs command a price roughly double that of ordinary boiled eggs. Proponents claim the concoction prevents heatstroke and improves health, and the practice is officially recognized as intangible cultural heritage in Dongyang.
5 Shirako

Japan’s culinary landscape is famous for daring dishes, and shirako—the milt or sperm sacs of male fish—occupies a special niche. Harvested from species such as cod, anglerfish, salmon, and the notorious pufferfish, the sacs are collected during winter when the fish produce the most seminal fluid.
Chefs prepare shirako in various ways: raw, it appears as a soft, white blob reminiscent of scrambled brains; lightly cooked, it transforms into a creamy custard; or it can be battered and deep‑fried, yielding a crunchy exterior that encases a silky interior. Highly prized, some portions fetch over $100, with pufferfish milt—known as fugu shirako—considered the ultimate version.
4 Century Eggs

Eggs are a breakfast staple worldwide, yet in China a centuries‑old preservation method yields the eerie “century egg.” Also called thousand‑year egg or pidan, the delicacy is made by soaking duck, chicken, or quail eggs in a mixture of black tea, salt, lime, and wood ash for anywhere between seven weeks and five months.
The result is a gelatinous, Jell‑O‑like egg where the white turns amber to near black and the yolk becomes a firm, grey‑green sphere. Fungal growth creates snow‑flake patterns on the shell, and a strong ammonia scent permeates the egg. Often sliced and served as a side dish, the flavor is an acquired one, prized for its unique texture and visual appeal.
3 Bird’s Nest Soup

When you think of bird nests, you might picture twigs and straw, but Chinese cuisine elevates them to a luxury: bird’s nest soup. The nests are built by cave‑dwelling swiftlets using only their own saliva, which hardens into a delicate, porous structure. Harvesters climb high into caves, carefully extracting the nests before the birds lay eggs.
The collected nests are then simmered into a gelatinous soup or dessert, often described as having a texture similar to a Slush Puppie drink. However, the practice imperils swiftlet populations, as nests are taken multiple times a year, sometimes before the birds have reproduced, leading to declining numbers and raising ethical concerns about sustainability.
2 Shiokara

Japan’s regional specialties include shiokara, a fermented, salty paste made from marine animal parts—most commonly cuttlefish. The preparation involves cleaning the cuttlefish, slicing it, and mixing the meat with its own viscera and juices. The mixture then ferments for up to a month, developing a thick, brown, briny paste with a pungent, rotten‑seafood aroma.
Traditional eaters often gulp the entire mixture in one go, chasing it with a shot of whiskey. Variations exist using squid, sea urchin, fiddler crab, or sea cucumber, each offering a slightly different flavor profile, though many describe the taste as reminiscent of anchovies.
1 Stinkheads

Alaska’s frigid climate has inspired a truly extreme delicacy: stinkheads, or tepa. The preparation starts by catching a whitefish or salmon, which is then gutted, placed in a wooden barrel, covered with burlap, and buried to ferment for about a week. After fermentation, the head and guts are removed and eaten directly, resulting in a putrid, putty‑like mass.
While native Alaskans regard stinkheads as a traditional treat, the dish carries a high risk of botulism—the highest worldwide—due to the fermentation process. Some modern adaptations aim to reduce the danger, yet cases still occur, highlighting the delicate balance between cultural heritage and food safety.
