The nearby town of Nueva Helvecia is still known as 'Colonia Suiza' after the Swiss dairy farmers who settled it in the 1860s and helped establish Uruguay's dulce de leche tradition.
Milk and sugar are slow-cooked for hours into a thick caramel spread, jarred and sold at roadside dairy stands throughout Colonia department. It's eaten by the spoonful or spread on bread and pastries.
