Ingredients

  • 2 cups (6 ounces) sliced almonds
  • 1 tablespoon canola or safflower oil
  • 8 ounces (2 sticks) unsalted butter, cut into small pieces
  • 3/4 cup (5 ounces) granulated sugar
  • 3 tablespoons water
  • 1/4 teaspoon kosher or fine-grained sea salt
  • 1 teaspoon pure vanilla extract
  • 1/4 teaspoon baking soda
  • 12 ounces bittersweet chocolate (62 to 72% cacao content), finely chopped
  • 7 x 11-inch (2-quart) rectangular baking pan

Method

  • Position a rack in the center of the oven and preheat the oven to 350F.
  • Place the almonds in a cake or pie pan and toast in the oven for 12 to 14 minutes, until light golden.
  • Stir the almonds every 5 minutes as they are toasting to ensure they brown evenly.
  • Remove the pan from the oven and cool completely on a rack, then chop the almonds finely.
  • Line a 7 x ll-inch (2-quart) rectangular baking pan with aluminum foil so that the foil fits snuggly in the pan and hangs a bit over the edges.
  • Using a paper towel, oil the foil that lines the inside of the pan.
  • Sprinkle 3/4 cup of the chopped toasted almonds over the bottom of the pan.
  • Melt the butter in a 3-quart heavy-duty saucepan over medium heat.
  • Add the sugar, water, and salt and cook, stirring constantly with a heat-resistant spatula, until the mixture registers 260F on a candy thermometer.
  • Immediately stir in 1/2 cup of the chopped almonds and continue cooking the mixture until it becomes golden brown and registers 290 on the candy thermometer.
  • Immediately stir in the vanilla and baking soda.
  • Be careful as the mixture will bubble and foam.
  • Turn the toffee out into the prepared pan and spread it evenly in the pan and to the edges.
  • Immediately sprinkle the top of the toffee evenly with the chocolate.
  • Let it stand for 2 minutes, until the chocolate begins to melt.
  • Use a small offset spatula to spread the chocolate evenly over the top of the toffee.
  • Sprinkle the top of the chocolate evenly with the remaining 3/4 cup of chopped toasted almonds.
  • Let the toffee set up at room temperature until firm, about 30 minutes, then refrigerate for 15 minutes to set the chocolate.
  • Lift the toffee from the pan by holding the overhanging edges of foil.
  • Peel the foil away from the toffee and break the toffee into small pieces.
  • Serve at room temperature.
