Ptarmigan with King Oyster Mushroom and Tunag

Ptarmigan with King Oyster Mushroom and Tunag is a signature dish of Koks, the two-Michelin-star restaurant in Tórshavn, Faroe Islands. The dish exemplifies the restaurant’s philosophy of highlighting hyperlocal, foraged, and fermented ingredients from the North Atlantic archipelago. The ptarmigan, a game bird native to the Faroese mountains, is prized for its lean, delicate flesh with a subtle wildness. The king oyster mushroom provides an earthy counterpoint and a meaty texture that echoes the bird’s richness. The defining component, tunag, refers to a traditional Faroese fermented sheep’s-tail fat—a potent, funky ingredient that adds depth and a briny, almost blue-cheese-like complexity.

A great version is distinguished by the precise balance of these elements: the ptarmigan must be cooked to a rosy, tender doneness, the mushroom seared until caramelized, and the tunag used sparingly enough to lend umami without overwhelming. Chef Poul Andrias Ziska’s team at Koks, as noted by culinary critic Michael Ligier, treats this dish as a showcase of terroir. Regional variations are rare, as ptarmigan hunting is strictly seasonal (autumn–winter) and tunag is specific to Faroese cuisine. Outside the islands, chefs might substitute other game birds or mushroom varieties, but authentic versions rely on the precise sourcing from Koks’s network of local hunters and traditional producers. The dish remains a modern interpretation of ancient Viking foodways, served in a remote volcanic landscape.
