GRANDMA'S BEST CHOCOLATE FUDGE

Steps:

• Butter an 8-inch square pan or dish. Thoroughly combine dry ingredients in a large, heavy saucepan. Stir in milk. Bring to a full rolling boil on medium heat, stirring constantly. Then boil, without stirring, until mixture reaches soft ball stage (234°F on a candy thermometer). Bulb of candy thermometer should not rest on bottom of pan. Do not stir. Remove from heat.
• Add butter and vanilla to mixture, but do not stir. Allow mixture to cool, at room temperature, to 110°F degrees (pan is barely warm to the touch). Beat until fudge thickens and begins losing its gloss. Quickly spread in pan. Let harden, and cut into squares.
