Chancaca is a typical Bolivian, Peruvian and Chilean sweet sauce made of raw unrefined sugar crystallized with honey. It is often flavored with orange peel and is consumed on sopaipillas or picarones.
William Lewis Herndon, in his 1854 journal [http://en.wikisource.org/wiki/Exploration_of_the_Valley_of_the_Amazon,_Vol.I ] Exploration of the Valley of the Amazon, Vol.I, Chapter VII.; "SION" p. 152-3 wrote:
August 14, 1853. We employed the morning in cleaning the aims and drying the equipage. Had a visit from some ladies, pretty Mestizos, who examined the contents of our open trunks with curiosity and delight. They refrained, however, from asking for anything until they saw some chancaca with which we were about to sweeten our morning coffee, when they could contain themselves no longer; but requested a bit. This seems an article of great request, for no sooner had the news spread that we had it than the alcalde brought us an egg to exchange for some; and even the lieutenant governor also expressed his desire for a little."
