Sweet potatoes, a humble root vegetable, hold a special place in Korean cuisine and culture. Beyond just a nutritious food source, they evoke nostalgia, represent comfort, and feature prominently in both traditional and modern dishes. But when we talk about sweet potatoes in Korea, we’re not just talking about one generic variety. Understanding the specific types, their characteristics, and how they are enjoyed is key to appreciating this staple food. This article will delve into the world of Korean sweet potatoes, or “goguma” (고구마), exploring the most popular varieties, their culinary uses, and their cultural significance.
The Allure of Goguma in Korean Culture
Goguma is more than just a food item in Korea; it’s woven into the fabric of Korean life. It’s a popular snack, a nutritious meal, and a symbol of warmth, especially during the colder months. Street vendors roasting goguma in large metal drums are a common sight in winter, filling the air with a sweet, smoky aroma. The warm, sweet flesh provides a comforting treat against the chilly weather.
The sweet potato has also gained significant traction as a diet food. Its high fiber content and relatively low glycemic index make it a popular choice for those looking to manage their weight or blood sugar levels. This has further cemented its place in Korean households and restaurants.
Furthermore, goguma is often associated with childhood memories. Many Koreans fondly recall eating roasted sweet potatoes with kimchi, a simple yet satisfying meal. This nostalgic connection further enhances its appeal.
Exploring the Primary Types of Korean Sweet Potatoes
While various sweet potato cultivars are grown globally, Korea primarily favors a few specific varieties that are particularly well-suited to the local climate and culinary preferences. These varieties are distinguished by their flesh color, texture, and sweetness levels. The most common and well-loved types are detailed below.
밤고구마 (Bam-goguma): The Chestnut Sweet Potato
Bam-goguma, meaning “chestnut sweet potato,” is arguably the most popular type in Korea. It is known for its relatively dry, crumbly texture, reminiscent of cooked chestnuts. Its flesh is typically a pale yellow color, and its sweetness is moderate, providing a subtle, earthy flavor.
The appeal of bam-goguma lies in its unique texture. Unlike its counterparts, it doesn’t become overly soft or mushy when cooked. Instead, it retains a slightly firm, almost granular consistency. This makes it ideal for roasting or baking, where the edges can caramelize and develop a slightly crispy exterior while the inside remains fluffy.
Its lower moisture content also makes it suitable for processing into flour or other dry goods. It’s often used in traditional Korean desserts and snacks, where its unique texture adds an interesting element. The subdued sweetness allows for other flavors to shine through, making it a versatile ingredient.
How to Enjoy Bam-goguma
Bam-goguma is most commonly enjoyed roasted. The roasting process intensifies its natural sweetness and creates a delightful contrast between the slightly caramelized exterior and the fluffy interior. It’s often paired with kimchi or a glass of milk for a simple yet satisfying meal.
It is also used in various Korean dishes. You might find it added to stews or soups for added sweetness and texture. It can also be mashed and used as a filling for dumplings or pastries. Its versatility makes it a beloved ingredient in Korean kitchens.
호박고구마 (Hobak-goguma): The Pumpkin Sweet Potato
Hobak-goguma, translating to “pumpkin sweet potato,” is characterized by its vibrant orange flesh and significantly sweeter flavor compared to bam-goguma. It has a moist, almost creamy texture that melts in your mouth. The sweetness is reminiscent of pumpkin, hence the name.
The high moisture content of hobak-goguma makes it exceptionally soft and tender when cooked. It’s often described as having a melt-in-your-mouth texture, which contributes to its popularity. The vibrant orange color is due to its high beta-carotene content, making it a nutrient-rich choice.
Because of its sweetness and soft texture, hobak-goguma is often enjoyed as a dessert or snack. It requires minimal preparation and can be steamed, roasted, or microwaved for a quick and healthy treat. It’s also used in various sweet dishes and beverages.
Culinary Uses of Hobak-goguma
Hobak-goguma is frequently used in sweet potato lattes (goguma latte), a popular beverage in Korea. Its natural sweetness and creamy texture blend perfectly with milk and other flavorings. It’s also used in desserts like sweet potato cakes, puddings, and sweet potato bread.
Aside from desserts, hobak-goguma can also be incorporated into savory dishes. Its sweetness adds a unique dimension to stir-fries, salads, and even kimchi. Its vibrant color also makes it an attractive addition to any dish.
꿀고구마 (Kkul-goguma): The Honey Sweet Potato
Kkul-goguma, or “honey sweet potato,” is a relatively newer variety that has gained immense popularity in recent years. It’s essentially a super-sweet version of hobak-goguma, with an even more intense sweetness and a stickier, almost honey-like texture.
The defining characteristic of kkul-goguma is its exceptional sweetness. It’s significantly sweeter than both bam-goguma and hobak-goguma, making it a favorite among those with a sweet tooth. The high sugar content also contributes to its sticky texture, which some find incredibly appealing.
Kkul-goguma is typically smaller in size compared to other varieties, and its skin is often a deeper reddish-purple color. When cooked, its flesh becomes incredibly soft and almost translucent, with a syrupy consistency. It’s often enjoyed as a simple snack or dessert.
Why Kkul-goguma is So Popular
The intense sweetness of kkul-goguma is the primary reason for its popularity. It provides a satisfying sweet fix without the need for added sugar or artificial sweeteners. This makes it a healthier alternative to many processed desserts.
It’s often roasted at a low temperature to allow the sugars to caramelize and intensify the flavor. The resulting sweet potato is incredibly soft, sticky, and bursting with sweetness. It’s often enjoyed on its own or paired with a scoop of ice cream for a decadent treat.

What are the most common types of sweet potatoes (goguma) eaten in Korea?
The two most prevalent types of sweet potatoes consumed in Korea are bam-goguma (밤고구마) and hobak-goguma (호박고구마). Bam-goguma, meaning “chestnut sweet potato,” boasts a drier, starchier texture reminiscent of chestnuts. Its flesh is typically a pale yellow color and it retains a slightly firmer consistency even after cooking.
Hobak-goguma, translating to “pumpkin sweet potato,” is characterized by its moister, sweeter flavor and a vibrant orange flesh. This type is often preferred for its softer texture when cooked, similar to that of a pumpkin. Its higher moisture content contributes to a more syrupy and intensely sweet taste experience.
How are *bam-goguma* and *hobak-goguma* different in taste and texture?
Bam-goguma offers a less sweet and more subtly nutty flavor profile compared to hobak-goguma. Its drier, starchier texture makes it slightly crumbly when cooked, appealing to those who prefer a less gooey sweet potato. Many find it pairs well with milk or other beverages due to its less overwhelming sweetness.
Conversely, hobak-goguma is markedly sweeter and moister. Its texture becomes incredibly soft and almost creamy upon cooking, making it a popular choice for desserts or enjoying on its own. The intense sweetness and softer consistency offer a more decadent eating experience.
What are some popular Korean dishes that feature sweet potatoes?
Sweet potatoes are incredibly versatile in Korean cuisine. One popular preparation is goguma mattang, a candied sweet potato snack that’s both sweet and crunchy. These glazed sweet potato chunks are often enjoyed as a street food or a simple homemade treat.
Another common dish is goguma bap, sweet potato rice, where diced sweet potato is cooked directly with rice. This adds a subtle sweetness and a pleasant textural contrast to the plain rice, making it a wholesome and flavorful meal. Furthermore, roasted sweet potatoes, whether bam-goguma or hobak-goguma, are a ubiquitous and beloved snack, particularly during the colder months.
Where can I buy Korean sweet potatoes outside of Korea?
Finding Korean sweet potatoes can be relatively easy depending on your location. Major Asian grocery stores, particularly those specializing in Korean or East Asian ingredients, are the most likely places to find bam-goguma and hobak-goguma. Look in the fresh produce section, often alongside other root vegetables like yams and taro.
Online retailers specializing in international foods are another viable option. Websites that cater to Korean or Asian groceries often ship nationwide or even internationally. Be sure to check the origin of the sweet potatoes before purchasing to ensure they are the varieties you are looking for, as sweet potatoes from other regions may differ in taste and texture.
Are there any nutritional benefits to eating Korean sweet potatoes?
Korean sweet potatoes, like other varieties, are packed with essential nutrients. They are excellent sources of vitamins A and C, both important antioxidants that support immune function and overall health. Vitamin A is also crucial for vision and healthy skin.
Furthermore, they are rich in dietary fiber, which aids in digestion and helps regulate blood sugar levels. They also contain potassium, an important electrolyte for maintaining healthy blood pressure. The vibrant orange color of hobak-goguma signifies a higher concentration of beta-carotene, a precursor to vitamin A.
How are Korean sweet potatoes traditionally cooked?
Traditionally, Korean sweet potatoes are often roasted directly in a wood-fired oven or on an open fire. This method imparts a slightly smoky flavor and allows the natural sugars to caramelize, enhancing the sweetness. The skin becomes slightly charred, while the inside becomes soft and fluffy.
Steaming is another common method, particularly for those who prefer a softer texture and a more delicate flavor. Steaming preserves moisture and allows the natural sweetness of the sweet potato to shine through. Both methods are relatively simple and require minimal ingredients, allowing the quality of the sweet potatoes to truly stand out.
Can I use regular sweet potatoes as a substitute for Korean varieties in recipes?
While regular sweet potatoes can be used as a substitute, be aware that the taste and texture will differ. American sweet potatoes are generally closer to hobak-goguma in terms of sweetness and moisture content, but even then, the flavor profile won’t be exactly the same. Consider adjusting the amount of sugar in the recipe if using a less sweet variety.
If the recipe calls for bam-goguma, using a purple sweet potato or a drier yam variety might be a closer substitute. However, the best results will always be achieved by using the specific type of Korean sweet potato called for in the recipe, if possible. Experimentation can be fun, but understanding the distinct characteristics of each variety will help you achieve the desired outcome.
