Dulce de leche is an Argentine confection that is made from milk. It consists in a bronze colored cream that resembles the taste and texture of caramel. It is native of Latin America, where, in Spanish speaking countries it is generally called dulce de leche and in Portuguese speaking countries it is called doce de leite. In both cases, the name translates to "sweet made of milk".
The correct pronunciation of dulce de leche in Spanish is Dool-seh deh leh-cheh. The important thing to remember when pronouncing dulce de leche is to keep the "e"s open and not to pronounce them as "ee". Further, the first "c" must be pronounced as if it were an "s".
