In a small saucepan, mix milk and sugar. COok over medium heat, stirring constantly until mixture comes to a boil. Boil 3 minutes. Remove from heat. Stir in chocolate and rum. Chill until cool enough to handle. Shape into balls. Coat as desired.
Coating options: instant hot chocolate mix, icing sugar, coconut, crushed nuts.
I usually put them in those mini-cupcake cups for serving.
Enjoy! Higs, Katherine
