This document discusses dulce de leche, a traditional jam from Latin America and Spain. It is made from milk, sugar, and vanilla and can be used in many desserts like cakes, ice cream, and alfajores. There are three main types - classic for home use which is soft and brilliant, repostero for bakeries which is dense, and ice cream flavor for industry which is very brilliant and tasty. The origin of dulce de leche came from an accident in 1829 when a maid left milk and sugar cooking over the fire too long and discovered the tasty substance.
