A grandmother is seen drying star fruit in front of her house. Leatherback is one of the spices of cuisine in aceh province, Indonesia. To become a kitchen spice, star fruit must be changed to Sunti acid.
To turn star fruit into kitchen spices, first soak the picked star fruit. Star fruit can be soaked a day or more until the green star fruit turns yellow. Then the starfruit is dried to dry in the drying stage of starfruit watered with salt to add wry.
This is not starfruit. I think this is bilimbi, probably.
