Brigadeiro

In a medium heavy-bottomed saucepan (not non-stick — you need to see the color change on the pot bottom), combine the condensed milk, butter, sifted cocoa powder, and salt. Stir together with a heat-proof spatula before turning on the heat, making sure the cocoa is fully incorporated before any heat is applied — this prevents scorching lumps. Place over medium-low heat.

Cook the mixture over medium-low heat, stirring continuously with the spatula in long, slow strokes across the entire bottom of the pan — never stop stirring. The mixture will gradually thicken. After 8–12 minutes, it will begin to pull away from the sides and bottom of the pan as you drag the spatula through. This is the critical test: drag a line across the bottom of the pan with your spatula. If the line holds clear for 3 seconds before the mixture flows back together, it is ready. Remove from heat immediately.

Pour the cooked mixture onto a greased plate or into a shallow bowl. Do not scrape the pot — the bottom layer that stuck will taste bitter. Spread slightly with the spatula. Let cool completely to room temperature (30 minutes minimum), then refrigerate for at least 30 minutes. Cold brigadeiro is essential for rolling — warm brigadeiro will stick to your hands and cannot form clean spheres. The mixture should be firm enough to scoop and hold its shape.

Lightly grease your hands with butter. Using a small spoon or melon baller, scoop portions of about 1.5 tablespoons each. Roll each portion between your greased palms in a circular motion, applying gentle, even pressure to form a smooth sphere. Work quickly — the warmth of your hands begins to soften the brigadeiro. Roll each ball immediately in the chocolate sprinkles, pressing gently to adhere, then place in a paper candy cup. If the mixture becomes too soft to roll, chill your hands under cold water and pat dry before continuing.
