The drink is made by dissolving a solid block of raw sugar straight from the cane mill, so its flavor changes slightly from batch to batch depending on how the sugar was boiled that day.
A block of unrefined cane sugar (tapa dulce) is dissolved in hot water, sometimes with a stick of cinnamon or a splash of milk. Vendors near Cartago's rural trapiches (cane mills) in the Orosi Valley serve it hot in cups to workers and travelers.
