Instead of throwing out the leftover coffee why not reuse it? Try making coffee ice cubes, you will notice it’s easy to find ways to use the coffee cubes once you have them. When you are ready to drink that hot cup of coffee but don’t want to burn your tongue just add a coffee cube. A coffee cube can cool down a hot cup of coffee without watering it down, this is especially helpful for black coffee drinkers in a hurry. Another way to use these coffee cubes is in blender with some vanilla ice cream and then you have your very own coffee flavored ice cream blend.
