While you can make dulce de leche at home by caramelizing a can of sweetened condensed milk, it is a bit less time consuming to buy it if you can find a jar at a local market or specialty store. La Salamandra Dulce de Leche is an Argentinian brand that, for me, is fairly easy to find at stores and online. This dulce de leche has a great consistency, thicker than a caramel sauce and just as sweet, but much less sticky. It will ooze a little bit if you drop a dollop on ice cream, but it will also stick easily to a spoon, even at room temperature, without running off. The latter feature is especially good if you like to eat a spoonful by itself occasionally!
The milk caramel is made with milk, sugar and glucose, and is flavored with vanilla (there is also a little bit of baking soda “as an acidity control agent”). You can really taste the milk flavor in the finished caramel underlying the sweetness of the dulce de leche. The vanilla comes through, too, but is a minor player in the caramel. It’s smooth and very sweet, but it has a richness that keeps you coming back for more, unlike some (cheaper) caramel sauces that just seem to burn your throat with too much sugar.
I really like this brand and would recommend keeping an eye out for it, whether you’ve had other brands or want to give dulce de leche a try for the first time.
