Dried chillies are one of the most important spices in Southeast Asian cuisine when it involves a spicy dish. Sun-drying is the most natural method when it comes to drying the chillies as it requires no preparation. Direct sunlight and heat are the only success factors to ensure a bountiful supply of dried chillies. Fresh chillies are dried under the sun for at least 3 days. The moisture available in the chillies should be brought down to 10% to ensure that it stays flavourful and retain its colour. Once dried, the chillies are sold as they are or further processed into chilli powder.
