Seonggi Miyeokguk (성게미역국)

Seonggi miyeokguk is a Jeju Island specialty of Korean seaweed soup elevated with fresh sea urchin (seonggi). The dish builds on miyeokguk, a traditional birthday soup made from wakame seaweed, whose origins trace to a legend that a mother who ate seaweed soup after childbirth recovered quickly. In Jeju, the addition of sea urchin transforms the humble soup into a luxurious, coastal delicacy. Key ingredients include rehydrated miyeok (seaweed), sea urchin gonads, a clear broth often seasoned with sesame oil, soy sauce, and minced garlic, and sometimes a touch of salt from the sea. A truly great version distinguishes itself through the quality of the sea urchin—it should be sweet, briny, and melt into the broth—and the seaweed’s texture, which must be tender but not mushy. The broth itself should be clean and light, allowing the umami of the sea urchin to shine without overwhelming the palate. Regional variations are subtle: on mainland Korea, miyeokguk is typically made with beef brisket or clams, while Jeju’s version relies almost exclusively on local seafood. This Jeju-style preparation is famously served at Kim Hwi Jeon (김희선 제주몸국) in Jeju City, a venue praised by food blogger Mark Wiens for its intensely savory, ocean-forward flavor. The restaurant’s dedication to fresh, local sea urchin captures the essence of what distinguishes a superior seonggi miyeokguk.
