What makes that Latte so sweet?
Cuban Coffee, called Cortado, is a specific way to make what might otherwise be called a Latte. You start with Cuban roast espresso beans— not burnt, like a French roast, but dark, rich, flavorful. Steam the milk just so— not as much big foam as in a Latte, but thickened with microfoam so it adds a dense, caramelly texture. Properly done, the sweetness comes from the milk, and contrasts pleasantly with the bitterness of the coffee.
You may like it with a small spoon of sugar, put real Cubanistas take it straight.
