Here’s the Brazilian version of the candy you call fudge. It’s named after a famous general and was created in the 1920s when imported sweets were unavailable during the upheaval of the time. Brigadeiro is one of the most popular candies in children’s parties.
Over medium-low heat, melt together milk, butter and chocolate mix powder, stirring vigorously. Cook until mixture thickens enough to pull away from pan bottom during stirring. Pour into parchment paper-lined (20 cm) square pan and let cool to room temperature.
Take small amounts of the mixture with a teaspoon or melon-baller and, with greased hands, make (2.5 cm) balls. Roll the balls in coatings, if using.
To test mixture firmness before rolling, take a small sample and dip it in a glass with cold water. If cooked enough, this sample should hold its shape after cooling down in the water.
