Palm sugar is a sweetener derived from any variety of palm tree. Palm sugar is sometimes qualified by the type of palm, as in coconut palm sugar. While sugars from different palms may have slightly different compositions, all are processed similarly and can be used interchangeably.
Palm sugar is produced by boiling collected sap until it thickens. The boiled sap can be sold as palm syrup. It is sold in bottles or tins and tends to thicken and crystallise over time. The boiled sap can also be solidified and sold in the form of bricks or cakes. It can range in colour from golden brown to dark brown or almost black, like Indonesian gula aren.
