1Melt butter in a saucepan.
Add sugar, water, and corn syrup.
Cook the mixture over medium heat, stirring.
2When the sugar dissolves and the mixture begins to boil, raise the heat and bring the mixture to 290 degrees Fahrenheit on a cooking thermometer. (This is called the soft crack stage). It will be light brown in color, and syrup will separate into threads that are not brittle when dribbled into cold water.
3Quickly stir in 1/2 cup chopped almonds.
Immediately pour the mixture onto an ungreased baking sheet. Wait 2 or 3 minutes for the candy surface to firm, then sprinkle on the chocolate chips.
In a few minutes, when the chips have softened, spread the chocolate evenly over the surface.
Sprinkle the remaining almonds over the melted chocolate. When the chocolate hardens, crack the candy into pieces. Store covered.
