Miyeok muchim (seaweed salad) is great when you are craving for something refreshing that will boost your appetite. A perfect trio: soft miyeok, crunchy radish and succulent cucumber, dressed with a sweet and sour vinaigrette is indeed invigorating to your taste buds. Miyeok muchim is traditionally served as one of the side dishes that complement rice for any meals but it can surely be a great appetizer as well. This recipe is a spicy version.

Miyeok is considered to be one of the super foods even in North America even though it's not in the normal American diet. It is a great source of calcium, iodine, fibre, omega acids, vitamin B1 & B3, while low in calorie. People believe that its health benefits are infinite: metabolism regulation, blood purification, constipation relief, detoxification, anti-carcinogen, anti-aging etc. For this reason, Korean women eat Miyeokguk (seaweed soup) after giving birth. They say this tradition started in the Goryeo Dynasty when people observed whales eating miyeok after giving birth (believe it or not).

Optional Ingredients and Substitutions

Dried miyeok: Depending on how dry the miyeok is, the amount of dried miyeok needed may vary. For dried "pre-cut" miyeok, you may need less because it increases more in volume than regular dried miyeok when soaked. After soaking for 30 minutes, it should be about 1½ cups for 2 servings (can be 4 servings if there are many other side dishes for the meal). However, you can add more miyeok if you love it.
Soy Sauce for Soup (Gook Gan Jan): You can use regular soy sauce or just add more salt.
Radish: Korean radish is best for this dish. But, if you cannot get it, use a western radish.
Sesame seeds: Can be omitted.
Gochujang & gochugaru: You can use a mix of both or either one. Gochujang (red chili paste) has sweetness and saltiness to it. So, if you are using more gochujang (red chili paste) and no gochugaru (red chili flakes), you may want to reduce the amount of salt or sugar. Depending on the spiciness you want, you can vary the amounts.
