Kdam Chaa Mrech Kampot
Khmer stir-fry of whole crab with green Kampot peppercorns, garlic and palm sugar.
Kdam chaa mrech Kampot (ឆាក្តាមម្រេច), or Kampot pepper crab, is a Khmer stir-fry of whole crab with green Kampot peppercorns, garlic and palm sugar.[1][2][3] It is a regional specialty of Kampot and Kep on Cambodia's southern coast.[4][3]
Cultural context
The dish is also called chhar kdam merec.[3] Its Khmer name is also written ក្តាមឆាម្រេចកំពត.[2] It is made by stir-frying crab with garlic, palm sugar, spring onions, fish sauce and green Kampot peppercorns, and it is served right away, often as a main dish.[2][3] It may also come as a starter or a sharing platter, or as a main dish with rice and green vegetables.[3] The taste is slightly sweet and gently spicy from the pepper.[4] Young green peppercorns still on the vine give a floral heat that does not overwhelm the sweet crab meat.[5]
Kampot is a town known for its pepper and seafood, and the writers at Sous Chef ate the dish by Kampot harbor as the fishing boats came in at sunset.[3] At the Kep crab market, local women gather blue swimmer crabs each day from traps in shallow water.[6] The crabs are sold live and may be cooked right at the market.[6] Fishermen have brought their catch straight to the Kep crab market for generations, which keeps the cooking simple.[5] At the Kep stalls, the crab goes from basket to wok within minutes and is served on a metal tray with baguette and a lime and pepper dip.[7] Diners crack the shells by hand, suck the sauce from the legs, dip bread in the juices and strip the peppercorns from their stems.[7] This pairing of coastal crab with Kampot pepper from just inland is a defining feature of the region's seafood cooking.[5]
Ingredients and preparation
One home-style method starts with a whole crab that has been boiled or steamed, cleaned and cracked.[3] The claws come off and the body is halved with a heavy cleaver.[3] The pieces fry briefly in oil before the seasoning goes in.[3] Fish sauce, soy sauce, palm sugar and water then make a seasoned liquid that steams the crab in the covered wok.[3] The pieces are stirred until the sauce coats the shells, and the crab is laid on a large sharing plate with rice and green vegetables.[3]
Another method fries the peppercorns and garlic first, then adds oyster sauce, fish sauce, sugar and a little water.[4] The crab cooks covered until its flesh turns opaque, and chives go in near the end.[4] A third sears the crab until the shells turn from bluish gray to bright orange, then covers it in a sauce of fish sauce, oyster sauce, soy sauce, palm sugar and stock and reduces it to a sticky glaze.[7]
The fresh green peppercorns are moist, mildly hot and very fragrant, and Cambodian cooks use them by the handful, more like a vegetable than a spice.[7] They are eaten as a main part of the dish alongside the crab.[7]
History and origins
The dish joins the crab of Kep's coast with pepper grown on trellised vines a short way inland in Kampot Province.[7] The pepper is the unripe berry, picked on the stem before it dries into black pepper or ripens into red.[7] Pepper has been grown in the region for centuries, and in the early twentieth century Kampot pepper became a prized French colonial export used in Paris kitchens.[7]
Under the Khmer Rouge, in Democratic Kampuchea (1975 to 1979), the pepper plantations were destroyed: farmers were forced to grow rice, and the vines were abandoned.[7] In the 1990s growers rebuilt Kampot pepper from a few surviving farms.[7] Kampot pepper later received protected geographical indication status, a legal mark tying a product to its place of origin, and the DishNomad Kitchen counts it as the first Cambodian product to obtain that status.[7]
Regional and household variations
Brined green peppercorns, rinsed well, can stand in for fresh ones.[7] Fresh green Kampot peppercorns are the usual choice, though Kampot black pepper can be used too.[3] The same wok method is used for squid rings, and large shell-on prawns can take the place of crab.[7] A dry-fried version leaves out the stock and cooks the crab with garlic, pepper and fish sauce alone.[7]
Some cooks add tamarind juice for sourness, though it is optional.[4] One household recipe allows soy sauce in place of fish sauce, with oyster sauce adding savory depth.[4] Beyond Kep and Kampot, it is sold in Sihanoukville at seafood markets and street stalls on the coast, where vendors cook the crab live and serve it hot.[1]
