Well.. I didn't write many information about this because there's a wikipedia and other sites own the information @brittandjosie😉 this fruit probably native to Mollucas or Maluku but can be found in Zanzibar and California (in a botanical garden) every South East Asia countries has their spesific food recipes using this fruit and off course only few old people who has been living or been in Indonesia know this fruit, very acidics😅
