How did I not think of this before?
Make a pot of regular coffee, let it cool, then pour into ice cube trays to freeze overnight.
Then, the next time you want a cup of iced coffee take another room temp pot, pour it over 7-8 of the cubes–stir, and enjoy!
I’ve tried cooling coffee before and then adding regular ice but the taste gets so diluted. This is the sure-fire way to get coffee-shop strength iced coffee.
