🍯 Dulce de leche

Dulce de leche is a thick caramel “milk jam” from Latin America, especially Argentina and Uruguay. The Argentine food code (Código Alimentario Argentino, Article 592) defines it as a product obtained by concentrating milk with heat and adding sucrose. The name “Dulce de Leche” is allowed only when the milk base contains no non-dairy fat or protein.

No more than 30 kg of sucrose may be added per 100 l of milk. The finished product may contain no more than 30% moisture, 6–9% fat, at least 5% protein and no more than 2% ash; above 9% fat it becomes “Dulce de Leche con Crema”. The texture is creamy, with no perceptible crystals, and the caramel-brown colour comes from the Maillard reaction between milk sugars and proteins. Argentina's 2006 premium quality protocol adds: cook it down to 69–74 °Brix, use no preservatives or whey powder, and fill it hot, from 60 °C, into glass or tins.

In the same protocol Argentina declared dulce de leche part of its gastronomic and cultural heritage. Other countries have their own names and versions: in Brazil it is doce de leite, and in Mexico cajeta is made from goat's milk.

Dulce de leche or condensed milk? Condensed milk is milk with sugar already concentrated, while dulce de leche is cooked further, until it turns caramel brown through the Maillard reaction and becomes thick and creamy with no crystals. Argentine law allows the name only when the milk base has no non-dairy fat or protein. Cousins exist elsewhere: doce de leite in Brazil and cajeta in Mexico, made from goat's milk. It is also different from boiled condensed milk, which is made by heating a sealed tin of the sweetened product.

On the label look for “Dulce de Leche”, the Spanish name in Argentina and Uruguay, and for the type: “Repostero” or “Pastelero” is firmer, with thickeners, for fillings and baking; “Heladero” is meant for ice cream; “con Crema” is richer. A premium Argentine product states no preservatives and no whey powder. You find it in jars or tins, in the spreads aisle of a supermarket, in Latin American shops and in delicatessens.

Why it matters to you. The label tells you the intended use: “Repostero” or “Pastelero” is firmer, with thickeners, for fillings and baking; “Heladero” is for ice cream; “con Crema” is richer. According to USDA, 100 g of dulce de leche has 315 kcal, 55.4 g of carbohydrates, 7.35 g of fat, 6.84 g of protein and 251 mg of calcium, so it is first and foremost a sweet.
