Miel de palma (lit. palm honey, also palm syrup) is an edible sweet syrup produced from the sap of a number of palms. It is produced in the Canary Islands and coastal regions of South America.
In the Canary Islands, palm syrup (miel de palma) is produced from the Canary Island Date Palm (Phoenix canariensis). In Chile, palm syrup (miel de palma) is produced from the endangered Chilean Wine Palm (Jubaea chilensis). Other species used include the coconut palm, sugar palm, and palmyra palm.
Most guarapo and miel de palma production occurs in the municipality of Vallehermoso on La Gomera. The process of collecting sap from the palm and concentrating it into syrup is similar in many ways to the process used for maple syrup.
The sap, known as guarapo or garapa, is collected from a bowl-shaped depression cut into the crown of the tree. As guarapo spoils quickly in sunlight, the harvesting is done overnight. Every evening during the harvesting season, the guarapero (farmer) prepares each tree. He climbs to the top of the tree, often using a ladder, uses a sharp knife or chisel to trim the bowl to remove surface crust and open the pores, and hoists a bucket into place beneath a pipe or channel leading from the bowl. Early the next morning, he returns and collects the filled buckets, containing ten or more litres from each tree.
The harvested guarapo is then brought to, or collected by, a local processing plant, or may be processed on site. Processing involves boiling the guarapo for several hours until it is reduced by about 90% to a dark brown syrup that is rich and sweet. It is then packaged, typically in glass jars. Palm syrup will tend to thicken and crystallize over time.
