1Preheat the oven to 350 degrees. Spread the almonds on a baking sheet and toast for about 6 minutes, until golden. Line a 17-by-11 inch rimmed baking sheet with lightly buttered parchment paper. Arrange the saltine crackers on the baking sheet in a single layer, patching any holes with cracker bits. In a medium saucepan, combine the sugar, butter and corn syrup and cook over low heat until the sugar is melted. Cook the syrup over moderate heat without stirring until it starts to brown around the edges, about 5 minutes. Insert a candy thermometer into the syrup and simmer, stirring with a wooden spoon, until a honey-colored carmel forms and the temperature reaches 300 degrees, about 6 minutes longer. Slowly and carefully pour the carmel over the crackers, being sure to cover most of them evenly. Let cool for 3 minutes, then sprinkle the chopped chocolate evenly on top. Let stand until the chocolate is melted, about 3 minutes, then spread the chocolate evenly over the toffee. Spread the almonds over the chocolate. Freeze the toffee until set, about 15 minutes. Insert the toffee onto a work surface and peel off parchment paper. Invert again, break into large shards. The chocolate-almond toffee can be refrigerated for up to 2 weeks in an airtight container. Enjoy!
