Chocolate Fudge

Directions

1. 1
   In 2-quart saucepan, mix the first 4 ingredients. Bring to a full boil, stirring constantly, (I use a wooden spoon) on high heat. Set heat on medium (enough to keep boiling, but not scorch) for 6 minutes, without stirring.
2. 2
   Test for soft ball in cool water. Remove from heat and let cool for 10 minutes. Add margarine, salt and vanilla. Beat (approximately 8 to 10 minutes) until mixture begins to thicken.
3. 3
   Add walnuts, if desired, while beating. Quickly pour onto a platter (prepared with a paper towel under plastic wrap; the towel keeps the wrap from sticking to the platter).
4. 4
   Let cool thoroughly.
5. 5
   Cut into pieces with a pizza cutter.
