Beolgyo sits on Yeoja Bay beside Suncheon Bay, where the flats are so deep in fine silt that a person sinks, which is why gatherers push across the mud on a wooden sled, the ppeolbae; that mud-sled cockle fishery of Boseong was named a National Important Fisheries Heritage in 2015 and is described as a centuries-old tradition. Cockles are recorded as a Boseong specialty in a fifteenth-century gazetteer, and Beolgyo's fame is specifically for the prized true blood cockle. The cultural anchor is the novel The Tae Baek Mountains, a sprawling ten-volume work serialized through the 1980s and set in Beolgyo, in which the cockles feature; a literary museum opened in the town in 2008. By a documented turn, the word for the cockle shifted toward the local Jeolla pronunciation as standard Korean because the author insisted on it over his editor. Beolgyo is the renowned cockle ground and historic trading hub, though by some accounts a neighboring peninsula produces the larger share.

Plump, tender and juicy, the cockle meat is briny-sweet with a distinct faint iron note, popped straight from the half-open shell. Across the spread the textures shift: the dressed muchim chewy and savory with soy, sesame and chili, the soup deep with doenjang, the bibimbap nutty with seaweed flakes. The signature is the whole cockle itself, rare and blood-juicy, the warm liquor running as the shell parts. It is a hands-on, briny, deeply savory meal, every dish a different angle on the same shellfish.

Blood cockles are unusual among bivalves in carrying hemoglobin, the iron-based red pigment, in their blood, where most molluscs use a copper-based blue one, which is why the juice runs red and iron-rich and the meat tastes faintly metallic-sweet. The cooking is the point of pride: the water is held just below a rolling boil and the cockles go in for only a few minutes, stirred in one direction so the meat sets toward one side of the shell and shucks easily. They are pulled while the shells are barely cracked, and crucially they should not gape wide open, since a wide yawn means overcooking and oxidation that flattens the flavor; the brief, gentle parboil keeps the muscle from contracting tight, so the cockle stays tender rather than rubbery, the briny sweetness coming from its free amino acids.
