Samlor machu kroeung
Sour, herbal and gently golden from turmeric, samlor machu kroeung is one of the soups Phnom Penh families put on the table at lunch, ladled over rice with a side of something fried or grilled. Its base is a fresh kroeung of lemongrass, galangal, turmeric and kaffir lime, fried and simmered with slow-cooked beef until the broth turns aromatic, then soured with tamarind and finished with armfuls of crunchy morning glory. Many cooks use beef tripe; here it is braising beef, which turns spoon-tender. A slip that ruins it is adding the morning glory too early, so it turns khaki and slimy. Chef's tip: toast the kroeung in the beef fat until it darkens a shade and smells sweet; that is where the soup's depth comes from.
