Ingredients
2 teaspoons butter1 cup sugar1 cup dark corn syrup1 tablespoon vinegar1 tablespoon baking soda1 package (11-1/2 ounces) milk chocolate chips1 tablespoon shortening
Preparation
Line a 13x9-in. pan with foil and grease the foil with butter; set aside. In a large heavy saucepan, combine the sugar, corn syrup and vinegar. Cook and stir over medium heat until sugar is dissolved. Bring to a boil. Cook, without stirring, until a candy thermometer reads 300° (hard-crack stage).
Remove from the heat; stir in baking soda. Immediately pour into prepared pan. Do not spread candy. Cool. Using foil, lift candy out of pan. Gently peel off foil; break candy into pieces.
In a microwave, melt chips and shortening; stir until smooth. Dip candies into the chocolate mixture, allowing excess to drip off. Place on waxed paper; let stand until set. Store in an airtight container.
