Walk through any Korean traditional market, and somewhere between the fried chicken stall and the tteokbokki cart, you will smell something earthy, savory, and unmistakably alive. That smell is beondegi (번데기), boiled or steamed silkworm pupa served in small paper cups with a toothpick. It is one of Korea's most distinctive (and divisive) snacks, eaten by Koreans for generations and feared by most international visitors. The flavor, texture, and cultural weight of beondegi all make it worth understanding, even if you never plan to try it.
This guide walks through everything worth knowing about Korean beondegi: what it actually is, how it became part of Korean cuisine, what it tastes like, the canned and street-food versions, and how visitors usually react to their first bite.
What Is Beondegi?
Beondegi is a Korean snack made from the pupa (chrysalis stage) of the silkworm. The pupae are harvested as a byproduct of the Korean silk industry, then boiled or steamed in seasoned broth and served in small paper cups, plastic cups, or cans. The cooked beondegi has a chestnut-brown color, a slightly chewy outer shell, and a softer protein-rich interior with a flavor that sits between earthy, nutty, and faintly fishy.
The name itself literally means "pupa" or "chrysalis," and Koreans have been eating beondegi since at least the early twentieth century. Today, beondegi is sold by street vendors at markets, baseball stadiums, and amusement parks, packed into convenience-store cans, and occasionally cooked into a savory soup called beondegi-tang. The snack is also high in protein, low in fat, and surprisingly nutritionally efficient by traditional Korean standards.
The History of Beondegi in Korea
Beondegi became popular in Korea during and after the Japanese colonial period (1910 to 1945), when Korean silk farms produced enormous quantities of silk and the leftover pupae provided a cheap, protein-rich food for working-class Koreans. The snack's popularity grew during the Korean War and the postwar years, when food shortages made any inexpensive protein valuable.
By the 1970s and 1980s, beondegi had become a fixture at Korean markets, school zones, and amusement parks. Many older Koreans associate the smell of beondegi with childhood memories of after-school snacks or trips to Lotte World. Younger Korean generations are more polarized: some embrace it as cultural heritage, others avoid it entirely, viewing it as outdated or unappetizing.
What Does Beondegi Taste Like?
The honest answer is that beondegi tastes like nothing else in Western cuisine. The closest comparisons reviewers tend to reach for are roasted chestnuts (for the earthiness), boiled peanuts (for the texture), or sardines (for the slight fish-like savoriness). The outer shell pops slightly when bitten, and the inside has a soft, almost custardy quality.
The Korean seasoning is mostly soy sauce, salt, and a small amount of MSG, which gives the broth a savory base. Some street vendors add a touch of red chili pepper, ginger, or garlic to the boiling water for a more complex flavor. Beondegi is meant to be eaten warm, scooped from the cup one at a time with a toothpick.
Canned Beondegi: The Convenience Store Version
For the home cook, beondegi is also sold in cans at Korean grocery stores. The most common brand is Beondegi by Beksul or Dadam Foods, with the pupae pre-seasoned in soy broth and ready to heat. The canned version has a longer shelf life and somewhat softer texture than the fresh street version, but the flavor is roughly similar.
Canned beondegi is genuinely popular among older Korean adults who enjoy it as a small protein side dish with rice or as a beer snack. It is also a common Korean drinking food (anju) at older pojangmacha tents and dive bars, where the salty, slightly funky flavor pairs naturally with chilled beer or soju.
How First-Timers Actually React
Reactions to beondegi vary widely. Korean adults who grew up with it usually describe it as nostalgic and comforting. International visitors usually fall into one of three camps: surprised acceptance ("not as bad as I expected"), polite refusal ("I tried one, that was enough"), or genuine enthusiasm ("I get why people love this").
The most common complaints from first-timers are the smell (earthy, intense) and the texture (the popping shell). The most common praises focus on the umami depth and the surprising savoriness once the visual barrier is crossed. Beondegi is genuinely a cultural marker: Koreans who introduce non-Korean friends to beondegi often treat it as a kind of cultural threshold test.
Should You Try Beondegi?
If you are visiting Korea and feel curious, yes. The snack is harmless, traditional, and inexpensive (typically 1,000 to 2,000 won per cup at street markets). The best way to try beondegi for the first time is at a Korean traditional market like Gwangjang or Namdaemun, where the vendors are friendly and the small paper-cup format makes it a low-commitment experience.
Avoid the canned version for your first try. The street market version is fresher, hotter, and noticeably better flavored, and trying it in the cultural setting where it belongs is part of the experience. If you do not like it on the first bite, that is also a valid result: many Koreans do not eat beondegi either. The point is the cultural moment more than the snack itself.
