On medium heat cook sugar, evaporated milk, orange juice and butter to soft ball stage (to test: fill glass half full with cold water. Put spoonful of mixture into water and try to form a soft ball. If it won't form, keep boiling). Remove from heat and cool until lukewarm. Beat until translucent. When it thickens it will turn opaque and be fudge consistency. Add nuts and orange rind. Roll it up in wax paper and refrigerate until cool. Roll into balls and dip in chocolate.
