Satin Chocolate Sauce: In the top half of a double boiler, combine the 2 chocolates over simmering water. Stir constantly until melted, then whisk in the corn syrup and coffee without removing the double boiler from the heat. Whisk until smooth and shiny. (The sauce can be made up to 24 hours in advance and refrigerated. To rewarm, stir over low heat or heat in a microwave.)
Caramel Sauce: Pour the sugar into the center of a deep saucepan. Carefully pour the water around the walls of the pan, trying not to splash any sugar onto the walls. Do not stir; gently draw your finger twice through the center of the sugar, making a cross, to moisten it. Over high heat, bring to a full boil and cook without stirring, swirling the pan occasionally to even out the color, until medium caramel in color, 5 to 10 minutes. Immediately turn off the heat and use a wooden spoon to slowly and carefully stir in the cream (it will bubble up and may splatter). Set aside. If the sauce has cooled, rewarm it over low heat (or in a microwave) until softened.
Raspberry Sauce: Puree the berries with the sugar in a blender. Strain out the seeds through a strainer and keep chilled until ready to serve.
Using a small ice cream scoop, scoop out balls of ice cream and place them on a sheet pan in the freezer. One at a time, roll 1 flavor in the biscotti crumbs and the other flavor in the chopped almonds then return them to the freezer. Keep them in an airtight container until ready to serve, up to 2 days. Place the sauces in bowls or individual fondue pots if you have them and warm the chocolate fudge and caramel. Serve the sauces with the coated ice cream balls and some forks for dipping.
