Peranakan cooking, a Southeast Asian cuisine with multicultural roots, created and popularised by nyonyas (Peranakan women), is often labour-intensive and time-consuming. Sometimes it takes several days to prepare one dish. Take ayam buah keluak (chicken and black nuts stew) for instance. The buah keluak, a nut native to Malaysian and Indonesian mangroves, has to be soaked in water for three to five days, changing the water every day, before extracting the black paste inside the nuts.
