Fish and meat
As the country has an extensive network of waterways, freshwater fish plays a large part in the diet of most Cambodians, making its way into many recipes. Daily fresh catches come from the Mekong River, Bassac River and the vast Tonlé Sap. Fish is far more common than meat in Khmer cuisine and fish forms 60% of the Cambodian intake of proteins.[citation needed] Prahok itself is based on fish. Many of the fish eaten in Cambodia are freshwater fish from the Tonlé Sap or from the Mekong. Dried salted fish known as trei ngeat (ត្រីងៀត) are a favourite with plain rice porridge. The popular Khmer dish called amok uses a kind of catfish steamed in a savoury coconut-based curry. The small fish known as Trey Dang Dau are very common and are often eaten deep-fried.
While freshwater fish is the most commonly used meat in the Cambodian diet, pork and chicken
are also popular. Though not as common as in neighbouring Vietnam,
vegetarian food is a part of Khmer cuisine and often favoured by more
observant Buddhists.Pork is quite popular in making sweet Khmer sausages known as twah ko (ត្វារគោ). Beef and chicken are stewed, grilled or stir fried. Seafood includes an array of shellfish such as clams, cockles, crayfish,
shrimp and squid. Lobsters are not commonly eaten because of their
price, but middle-class and rich Cambodians enjoy eating them at Sihanoukville. Duck roasted in Chinese char siu style is popular during festivals. More unusual varieties of meat include frog, turtle, and arthropods (including tarantulas); these are difficult to find in Khmer cuisine abroad but are used in everyday dishes in Cambodia.
