Acar

Acar is a type of vegetable pickle of Maritime Southeast Asia, most prevalent in Indonesia, Malaysia, Singapore and Brunei. It is a localised version of Indian achar. It is known as atjar in Dutch cuisine, derived from Indonesian acar. Acar is usually prepared in bulk as it may easily be stored in a well-sealed glass jar in refrigerator for a week, and served as a condiment for any meals. Pickling originated in India around 2400 BCE, and with expansion of Indian cultural influence on Greater India, through transmission of Hinduism leading to Indianisation, and the formation of native Southeast Asian kingdoms which adopted many Indian cultural elements, including food processing techniques. Through examining the etymology, the similar sounding name strongly suggests that indeed acar was derived from the Indian achar pickle. Indian achar was transmitted in antiquity to the maritime realm of Southeast Asia, which today is recognized as acar in Indonesia, Malaysia, Singapore and Brunei, and then on to the Philippines as atchara. The adoption of this vegetable pickling technique possibly took place during the Srivijaya period between 7th to 13th century.
