- Hot Fudge Sauce
- 1/2 pound bittersweet chocolate, coarsely chopped
- 1 cup water
- 6 tablespoons sugar
- 1/4 cup light corn syrup
- 1/4 cup unsweetened cocoa powder
- 1 tablespoon instant espresso mixed with 1 teaspoon water
- Caramel Sauce
- 1 cup sugar
- 1 tablespoon light corn syrup
- 1 cup heavy cream
- 2 tablespoons unsalted butter
- For the Sundaes
- Vanilla ice cream
- 1/2 cup chopped nuts
- MAKE THE HOT FUDGE SAUCE: Melt the chocolate in a small saucepan set in a larger pan of simmering water; stir until smooth. Meanwhile, in a medium saucepan, combine the water with the sugar and corn syrup and bring to a boil over high heat. Whisk in the cocoa powder, reduce the heat to moderate and cook, stirring, until slightly thickened, about 3 minutes. Remove the pan from the heat and whisk in the melted chocolate and espresso dissolved in water.
- MAKE THE CARAMEL SAUCE: In a medium saucepan, combine the sugar and corn syrup and cook over moderately high heat, without stirring, until a deep-amber caramel forms, about 6 minutes. Using a wet pastry brush, wash down any crystals from the side of the pan. Remove the pan from the heat and carefully stir in the cream and butter; the sauce will bubble up. Cook the caramel sauce over moderate heat for 5 minutes, stirring occasionally.
- MAKE THE SUNDAES: Spoon the ice cream into sundae glasses or bowls. Top with the hot fudge and caramel sauces, sprinkle with nuts and serve.
