Wild-caught Pacific sea cucumber skin, sold by the pound at Costco warehouse. This is the outer skin of the sea cucumber — a prized delicacy in Chinese cuisine and other East Asian culinary traditions. The skin has been pre-cooked in hot water and salted, making it ready to incorporate into soups, braises, and stir-fries with minimal preparation.

Sea cucumber skin is valued for its firm, gelatinous texture and its ability to absorb the flavors of rich sauces and broths. It is frequently used in traditional dishes alongside ginger, green onion, and soy-based sauces. The salted, pre-cooked preparation means it can be rinsed and used directly, though soaking before cooking is often recommended to reduce saltiness and achieve the desired tenderness.

As a wild-caught Pacific seafood product, sea cucumber is naturally low in fat and a source of protein, and has been used in traditional wellness practices throughout Asia for generations.
