1 (13 oz.) can evaporated skim milk, undiluted
1/3 c. cocoa
1/3 c. sugar
1/4 tsp. salt
18 regular marshmallows

1. Pour all but 1/2 cup evaporated skim milk into large bowl; freeze milk until ice crystals form throughout (about 1 hour).

2. Meanwhile, in a medium saucepan, stir cocoa, sugar and salt until well mixed; slowly stir in reserved 1/2 cup evaporated milk. Heat mixture over low heat, stirring constantly, until sugar is dissolved; add marshmallows and cook stirring constantly until melted, about 15 minutes. Cool mixture to lukewarm, about 30 minutes.
