Kokotxas are a delicacy in San Sebastian, particularly for seafood lovers. These tender and flavorful morsels come from the cheeks of hake or cod fish. They are often cooked in a pil-pil sauce, made with olive oil, garlic, and chili peppers, resulting in a rich and creamy dish. Kokotxas are typically served as a pintxo or as a main course in many traditional Basque restaurants.
