I challenged a dish called "Hoi Kreng," a type of red clam with dark red flesh, in Thailand.
Prying open the clam and tasting it with a refreshing sour sauce makes you crave beer. The blood-red color, likely from hemoglobin, and iron-rich appearance seem perfect for those opposed to the Belmont family.

Overview and Origins of Hoi Kraeng
Hoi Kraeng (หอยแครง / Hoi Kraeng) is a traditional Thai shellfish dish that uses blood cockles (English: blood cockle, scientific name: Anadara granosa) as its main ingredient. It is especially popular in regions abundant with fresh seafood, such as central Thailand and the areas around Bangkok, including the Amphawa Floating Market. Hoi Kraeng is traditionally served steamed or lightly boiled, with the shell opened and the flesh removed. It is commonly eaten by dipping it into a spicy and tangy seafood sauce.
Preparation, Festivals, and Role in Food Culture
Hoi Kraeng is readily available in various markets, food stalls, and popular seafood restaurants throughout Thailand. The cooking method is extremely simple; in most cases, the cockles are boiled or steamed for only a short time, which preserves their moist and springy texture as well as their characteristic iron-rich flavor and rich umami.
In Thailand, Hoi Kraeng is enjoyed alongside other shellfish such as snails, and is regarded as an essential flavor of everyday life in Isan, Bangkok, and other regions. It also pairs exceptionally well with alcoholic beverages like beer and shochu, making it a frequent feature at barbecues and social gatherings.
Nutritional Value and Biological Characteristics
The blood cockles used in Hoi Kraeng are distinguished by their reddish-black flesh, a result of their high content of hemoglobin and iron. Thanks to this abundance of iron, the dish has certain reputations as a remedy for anemia and as a source of high-quality protein. Cockles are also rich in zinc, vitamin B12, and omega-3 fatty acids, making them appealing to health-conscious consumers.
Internationally Similar Dishes and History
Dishes featuring blood cockles are not unique to Thailand, but are widely eaten throughout Southeast Asia, including southern China, Vietnam, Malaysia, and beyond. In China's Fujian and Guangdong provinces, they are commonly known as "xuehan" (血蚶) and are often served as a porridge topping or as an appetizer. In Japan, the same species is called "akagai" and is enjoyed in sushi, sashimi, or simmered with soy sauce.
Hygiene and Cultural Considerations
Because of their dark red flesh, blood cockle dishes require particular attention to hygiene, especially when undercooked, as there are risks of norovirus and hepatitis A virus. At Thai markets, only the freshest cockles should be selected, and consumption from reputable vendors is strongly recommended.
Moreover, blood cockles are considered taboo in certain religious dietary practices (for example, in some Buddhist communities), so it is advisable to check in advance when dining locally.
Symbolism in Food Culture
Hoi Kraeng is a symbol of the bounty and freshness of Thailand’s waterways and is considered an indispensable ingredient in the country's food culture. Especially when enjoyed at traditional markets such as the Amphawa Floating Market, Hoi Kraeng is highly favored by both locals and tourists.
