1 teaspoon butter, softened1 cup sugar3/4 cup light corn syrup2 ounces unsweetened chocolate, chopped1-1/2 cups heavy whipping cream, divided

In a large heavy saucepan, bring the sugar, corn syrup and chocolate to a boil over medium heat; stir until smooth. Add 1/2 cup cream; cook, stirring constantly, until a candy thermometer reads 234° (soft-ball stage). Add another 1/2 cup cream; return mixture to 234° (soft-ball stage). Add the remaining cream; cook to 245° (firm-ball stage).

Immediately pour into prepared pan (do not scrape saucepan). Let stand until firm, about 5 hours or overnight. Using foil, lift candy out of pan. Discard foil; cut candy into 1-in. squares using a buttered knife. Wrap individually in waxed paper; twist ends.
