Is Cat Ba horseshoe crab delicious? The answer depends on personal taste, but it has a distinctive flavor that differs from more common types of seafood. Horseshoe crab meat is firm and slightly chewy and is often paired with seasonings to create a richer taste.
One of the highlights of horseshoe crab is its variety of cooking methods. Visitors can try grilled horseshoe crab to appreciate its natural flavor, sweet-and-sour stir-fried horseshoe crab for a more pronounced taste, or horseshoe crab salad for a lighter option. Horseshoe crab is also a seasonal ingredient, so it may not be available at every restaurant year-round. If you want to try it, it is advisable to ask the restaurant about availability on the day of your visit.
An important note: horseshoe crab can look similar to the potentially toxic mangrove horseshoe crab. The latter contains toxins and should not be used as food. Visitors should not buy or prepare horseshoe crab themselves unless they have the knowledge needed to distinguish between the two species and prepare them safely.
