Whole crab stir-fried hard and fast with clusters of fresh green Kampot peppercorns still on the stem, garlic, fish sauce and palm sugar, so the sweet shellfish meets the bright, citrusy heat of the world-famous pepper.
This dish is the soul of the seaside towns of Kep and Kampot, where blue crabs are hauled straight from the bay and tossed with young peppercorns plucked fresh from nearby plantations. Kampot pepper earned protected geographical status in 2010, and its fragrant, almost citrus heat is what makes chha kdam mrech impossible to forget.
Sweet, briny crabmeat slides out of the shell glazed in a glossy savoury-sweet sauce, and the soft green peppercorns burst with a fresh, floral, lemony heat. It is messy, fragrant and built for cracking shells with your fingers.
Searing the crab in its shell over high heat caramelises surface sugars and locks in the sweet juices, while the brief covered steam finishes the dense meat. Fresh green peppercorns are milder and more aromatic than dried, lending citrus-floral heat without overpowering the delicate crab.
