Chocolate Walnut Fudge

• 2 squares unsweetened (2 ounces) chocolate
• 1/4 cup evaporated milk
• dash salt
• 2 cups sugar
• 1/4 cup (1/2 stick) butter
• 1/2 teaspoon vanilla
• 1/2 cup chopped walnuts

Directions for chocolate fudge.
Melt chocolate over very low heat. Add milk and salt; stir well. Stir in sugar and bring to a full boil over medium heat. Continue to cook, stirring only once or twice, until mixture forms a soft ball * (about 236° ) in about 1/2 cup cold water; remove from heat. Add butter and vanilla and stir to blend well. Stir in walnuts. Beat well with a large wooden spoon until mixture begins to thicken, then pour quickly into a buttered pie plate. Refrigerate; cut into squares when fudge is firm.
