I used my leftover almond to make chocolate covered pretzel rods with sprinkles, but you could use make regular chocolate covered pretzels. Or if you want to change it up, regular potato chips covered in chocolate are fantastic. Another idea would be to make a banana popsicle by splitting a banana in half and inserting a popsicle stick on the wide end and then dipping in chocolate. Or how about chocolate covered strawberries, cherries, or blueberries -- they all taste wonderful.
No need to throw away leftover melted chocolate because you had more than you needed for your recipe.
