When visiting Ha Long Bay, besides the famous squid cake on the culinary map, visitors also love Quang Ninh cù kỳ crab noodle soup, made from cù kỳ, a type of rock crab found in these waters.
Quang Ninh Cù Kỳ Crab Noodle Soup, a Must-Try Specialty in Ha Long
Diners visiting Quang Ninh Province are all curious about the cù kỳ specialty. Cù kỳ are related to crabs but have two large claws that are notably big compared with their body size, brown shells, and green eyes. Only the meaty claws of the cù kỳ are popular; its spongy body is not as rich or nutritious as the bodies of other crabs and swimming crabs.

Cù kỳ are easy to find at seafood markets in Ha Long. There are many culinary variations featuring this seafood, the most famous being cù kỳ crab noodle soup. This noodle dish originated among people living in fishing villages. During cù kỳ season, instead of only grilling or steaming them, they came up with another way to prepare them—as noodle soup—because cù kỳ contain a lot of roe and are suitable for making crab noodle soup.

Fresh cù kỳ are washed, with the claws and body separated, then steamed until cooked. The body is used to make the broth. The cù kỳ bodies are ground, strained to remove the solids, brought to a boil, and the meat is removed and set aside. The cù kỳ broth is then simmered with various types of seafood, dried shrimp, dried squid, tomatoes, and rice vinegar to create a richly sweet broth with a slight sour aroma.

The cù kỳ claws are carefully shelled so that the meat remains intact, making the bowl of noodles look appealing when served. The large, meaty claws are skillfully shelled, making them especially eye-catching and attracting diners as soon as the bowl of noodles is brought to the table.

Seated before a bowl of noodles with harmonious colors that stimulates both the eyes and the sense of smell, diners quickly scoop out several spoonfuls of crunchy pickled chili bamboo shoots from the glass jar, squeeze in some lime, add a piece of spicy chili, and enjoy it while the noodles are still piping hot.

During the rainy season, clumps of bamboo shoots weighing several kilograms are sold very cheaply. The bamboo shoots are peeled, cut into cubes, boiled, and then soaked with salt, chili, garlic, and sugar. This side dish is incredibly addictive with rice—and with cù kỳ crab noodle soup—as diners eat while exclaiming over its spiciness.
