Cambodia's most widely loved meat dish — cubes of marinated beef (or sometimes chicken) wok-fried until caramelised and served on a bed of lettuce and tomato, accompanied by a small bowl of lime juice mixed with freshly cracked Kampot black pepper and salt for dipping. The flavour contrast — tender, savoury beef with the bright, peppery citrus dipping sauce — is a Khmer culinary invention of understated genius. Found at almost every restaurant in the country and reliably excellent when made with quality pepper.
