1 C. (6 ounces) semisweet chocolate chips
2 C. packed brown sugar
1 C. light corn syrup
1/4 C. water

In a heavy saucepan over medium heat, melt remaining butter. Ad brown sugar, corn syrup and water. Cook and stir until mixture comes to a boil. Stir in the milk. Cook, stirring constantly, until a candy thermometer reads 248 degrees (firm-ball-stage). Pour mixture into prepared pan (do not scrape saucepan).
