      20 c  Popcorn (1 cup unpopped)

   Preheat oven to 300. Remove all unpopped kernels from popped corn. Put

   vinegar, and salt. Cook to 270 deg (soft-crack stage), stirring
   frequently (mixture should boil gently over entire surface).  Remove

   Stir just until mixed. Butter hands; using a buttered cup, sccop up
   popcorn mixture. Shape with buttered hands into 2-1/2 to 3-inch balls.
