It is a creamy sweet prepared with cooked milk, sugar and baking soda, plus some flavoring and flavoring. It is traditional from Argentina and has versions in other countries with different recipes (p. e.g. using goat's milk, cornstarch, vanilla and different amounts of sugar), and names like white delicacy, cajeta, delicacy, kajmak, arequipe, confiture de lait, milk sweet or doce de leite. There is a legend stating that the 'dulce de leche' was accidentally created in Cañuelas (province of Buenos Aires) by a cook of the caudillo and governor J. M . of Roses in the mid-nineteenth century, but this is also supposed to be an irony invented by J. L . Borges for a promotional item that was used in a campaign of the dairy company La Martona (also from Cañuelas), owned by the family of his friend A. Bioy Casares in the mid-twentieth century, reminiscent of another earlier legend where a Napoleon cook created the confiture de lait when he forgot a jug with milk over the fire.
