• 2 cups granulated sugar
• 3/4 cup light corn syrup
• 1/8 teaspoon salt
• 4 squares unsweetened chocolate
• 2 cups evaporated milk
• 1 teaspoon vanilla extract
• 1/2 cup chopped nuts

Gradually add remaining milk slowly, so that boiling does not stop. Continue cooking, stirring constantly, to firm-ball stage (248°F.). Remove from heat.
Stir in vanilla extract and nuts. Pour into buttered 8 inch square pan. When cold, turn out on cutting board and cut into 3/4 inch squares.
