1 Cù Kỳ Crab - A Unique Delicacy of the Coastal Region
1.1 A Brief Introduction to Cù Kỳ Crab
Cù kỳ is also known as cù kỳ crab, cùm crab, or rock crab because of its hard outer shell. It is a specialty commonly found in Vietnam’s coastal areas, particularly in Quảng Ninh.
Cù kỳ crabs usually have two large claws, brown shells, and green eyes, and often live in warm seas. This crab is famous for its firm, delicious meat, which can be prepared into many unusual and distinctive dishes. According to many food lovers, although cù kỳ meat is not especially sweet, it is tastier than swimming crab and more affordable, making it popular with many people.
This crab is called cù kỳ because it has a large shell, claws that curl inward, and moves more slowly than other sea crabs. Cù kỳ has a total of three pairs of legs, one pair fewer than sea crabs. At the same time, this species has two large, thick claws. These are also the main meaty parts of the cù kỳ, unlike its rather spongy body.
Currently, cù kỳ usually costs around 90,000 - 110,000 VND/kg, for approximately 9 small crabs. For large cù kỳ, 1kg contains around 5 or 6 crabs and costs approximately 120,000 - 170,000 VND. Hairy cù kỳ is more difficult to catch and therefore more expensive, usually ranging from 200,000 - 300,000 VND/kg for around 3 to 5 crabs. These are the prices at markets in Quảng Ninh. However, the prices are for reference only and may vary depending on the market period.
