1 can sweetened condensed milk
1 square unsweetened chocolate or 3 TBS. unsw. Cocoa
1 TBS. butter
½ tsp. vanilla
pinch of salt

Melt chocolate and add milk slowly. (If using cocoa, add milk slowly to cocoa so it won't go lumpy. Slowly cook on stove until a little thick. Remove from stove and add butter, salt and vanilla. Mix together. Dilute with regular milk to desired consistency. Good on ice cream.
