When traveling to Ha Long Bay, in addition to the famous squid patties on the culinary map, visitors also love Quang Ninh cu ky noodle soup, made from cu ky, a species of stone crab native to the local sea.
Quang Ninh Cu Ky Noodle Soup, a Must-Try Specialty in Ha Long
Diners visiting Quang Ninh Province are often intrigued by the cu ky specialty. Belonging to the crab family, cu ky is distinguished by its two claws, which are noticeably large compared to its body size, a brown shell, and green eyes. Only the meat-filled claws are widely favored, while the body is spongy, lean, and not as rich in nutrients as other crab species.

Cu ky is easy to find at seafood markets throughout Ha Long. There are many culinary variations of this seafood, the most renowned being cu ky noodle soup. This dish originated from local fishing villages. During the cu ky season, instead of merely grilling or steaming them, locals created this noodle dish because cu ky is packed with rich crab roe, making it perfect for cooking rieu-style broth.

Fresh cu ky is thoroughly washed, with claws and bodies separated before steaming. The bodies serve as the base ingredient for the broth. They are finely ground, filtered to remove residue, brought to a boil, and the meat is skimmed off and set aside. The broth is then simmered with an assortment of seafood, dried shrimp, dried squid, tomatoes, and fermented rice vinegar (giam bong) to achieve a deeply sweet flavor with a delicate hint of sourness.

The claws are peeled carefully so that the meat stays intact, ensuring an appealing presentation atop the bowl of noodles. The large, firm claws, skillfully de-shelled, are visually enticing and immediately capture the diners' attention the moment the steaming bowl is served.

To create an unforgettable bowl of Quang Ninh cu ky noodle soup, all seafood ingredients must be fresh. Fresh shrimp and mantis shrimp are steamed and shelled. Notably, they must be kept whole so the bowl looks stunning when plated. The shrimp are then lightly sautéed with a touch of cooking oil and seasoning.

During the rainy season, bamboo shoot clusters weighing up to two to three kilograms are sold at very reasonable prices. The bamboo shoots are stripped of their outer layers, diced into squares, boiled, and pickled with salt, chili, garlic, and sugar. This side accompaniment pairs exceptionally well with both rice and cu ky noodle soup, keeping diners savoring every bite with delight.
