Chocolate Marbled Fudge

2 cup Sugar
2/3 cup Heavy cream
1 cup Milk
1/4 cup Light corn syrup
1/4 tsp Salt
1 tsp Vanilla
2 1/2 oz Semisweet chocolate pieces, chopped

Combine the sugar, cream, milk, corn syrup and salt in a heavy, large saucepan.

Bring slowly to boiling, stirring constantly, until the sugar dissolves. boil gently, stirring occasionally, until mixture reaches 238F on the candy thermometer or soft ball stage. Remove from heat.

Cool for 5 minutes. Add the vanilla. Beat in vigorously until the mixture begins to thicken and lose its glossy look, about 5 minutes.

Pour half the fudge into a well buttered 8x8x2-inch baking pan.

Sprinkle evenly with half of the chocolate pieces.

Pour in the remaining fudge. Sprinkle with the remaining chocolate pieces. Cool completely on a wire rack. Cut into 1- inch squares.
