BRIGADEIROS

Steps:

• If using store-bought condensed milk, skip to Step 2. If making the sweetened condensed milk from scratch, add the milk and sugar to a large saucepan. Heat over medium-low, and simmer, stirring occasionally and scraping the sides and bottom of the pan with a spatula, for about 30 to 40 minutes. When the milk reduces to about 1 3/4 cups, thickens to a syrup texture and turns slightly yellow, it is ready.
• Prepare the brigadeiros: Melt the butter in a heavy skillet over low heat. Add the condensed milk, cocoa powder and salt, and whisk until no trace of cocoa remains, about 5 minutes.
• Turn the heat up to medium, and use a heatproof spatula to stir the mixture constantly until it becomes thick and shiny and pulls away from the bottom of the pan as a mass when you drag the spatula across it, about 7 minutes. If you're not sure the mixture is ready, take 1/2 teaspoon of it and run it under cold water. When it's cool enough to touch, squish it with your fingers - it should be the texture of a soft and fudgy caramel.
• Scrape all of the mixture onto a piece of parchment paper, and let it cool down until it's easy to handle, about 30 minutes. Lightly butter your hands, and use them to shape a scant tablespoon of the mixture into a ball or rough cube, then roll it in the sprinkles. Place each one on a paper wrapper, if you like. The brigadeiros will keep in the fridge for 1 week, or in the freezer for 1 month. Serve chilled or at room temperature.
