What are Korean sweet potatoes, and how do they differ from regular sweet potatoes?
Korean sweet potatoes, also known as ‘goguma’ in Korean, are a type of sweet potato that is native to Korea. They have a sweeter and nuttier flavor compared to regular sweet potatoes, with a firmer and starchier texture. Korean sweet potatoes are also smaller in size, typically ranging from 100 to 150 grams, and have a thinner skin that is often left on during cooking.
The main difference between Korean sweet potatoes and regular sweet potatoes is their starch content. Korean sweet potatoes contain more starch, which makes them ideal for boiling, roasting, or making into various Korean dishes such as ‘goguma latte’ or ‘goguma bingsu’. Regular sweet potatoes, on the other hand, have a softer and more moist texture, making them better suited for baking or mashing.
How long does it take to boil Korean sweet potatoes?
The boiling time for Korean sweet potatoes depends on their size and the desired level of doneness. Generally, it takes around 15-20 minutes to boil Korean sweet potatoes until they are tender. However, if you prefer a softer texture, you can boil them for an additional 5-10 minutes. It’s also important to note that the boiling time may vary depending on the altitude and the type of pot used.
To check if the Korean sweet potatoes are cooked, you can insert a fork or knife into the flesh. If it slides in easily, the sweet potatoes are done. You can also check for doneness by cutting into one of the sweet potatoes; if it’s tender and the flesh is easily mashed, it’s ready to be served. Be careful not to overcook the sweet potatoes, as they can become mushy and unappetizing.
What is the best way to boil Korean sweet potatoes?
To boil Korean sweet potatoes, start by washing them thoroughly and scrubbing off any dirt or debris. Then, place the sweet potatoes in a large pot and add enough cold water to cover them. Bring the water to a boil over high heat, then reduce the heat to medium-low and simmer for 15-20 minutes, or until the sweet potatoes are tender.
It’s also a good idea to add a pinch of salt to the water, as this can help to bring out the natural sweetness of the sweet potatoes. Additionally, you can add other aromatics such as garlic, ginger, or onions to the water for extra flavor. Once the sweet potatoes are cooked, drain the water and let them cool before serving.
Can I boil Korean sweet potatoes with their skin on?
Yes, you can boil Korean sweet potatoes with their skin on. In fact, leaving the skin on can help to retain the sweet potatoes’ natural sweetness and nutrients. Simply wash the sweet potatoes thoroughly and scrub off any dirt or debris before boiling them. The skin will come off easily once the sweet potatoes are cooked.
However, if you prefer to remove the skin, you can do so before boiling the sweet potatoes. Simply peel the skin off using a vegetable peeler or a sharp knife. Keep in mind that removing the skin may result in a slightly softer texture and a less intense flavor.
How do I store boiled Korean sweet potatoes?
Boiled Korean sweet potatoes can be stored in the refrigerator for up to 3 days. To store them, let the sweet potatoes cool completely, then wrap them in plastic wrap or aluminum foil and place them in a sealed container. You can also store them in an airtight container or zip-top bag.
When storing boiled Korean sweet potatoes, it’s essential to keep them away from direct sunlight and heat sources. You can also freeze them for up to 3 months; simply wrap the sweet potatoes tightly in plastic wrap or aluminum foil and place them in a freezer-safe bag. To reheat, simply thaw the sweet potatoes overnight in the refrigerator or reheat them in the microwave or oven.
Can I boil Korean sweet potatoes in advance?
Yes, you can boil Korean sweet potatoes in advance. In fact, boiling them ahead of time can help to save time during meal preparation. Simply boil the sweet potatoes as instructed, then let them cool completely before storing them in the refrigerator or freezer.
When boiling Korean sweet potatoes in advance, it’s essential to note that they may lose some of their texture and flavor over time. To minimize this, it’s best to boil them just before serving or to reheat them thoroughly before serving. You can also add a splash of water or broth to the sweet potatoes when reheating them to help restore their texture and flavor.
