This one is more for the Mommies' and Daddies' survival of the morning... with kids. Poor Man's Espresso.
I don't know about you, but we often have coffee left over after making a pot. Dh was reheating it in the microwave the next morning, rather than waste it. This morning I tried Poor Man's Espresso.
Take remaining coffee and pour it in the water container. Turn it on and have it run through the grounds from the previous morning again.
It gives it a stronger flavour and heats it all at once. It was actually very very good!
The next day's brew will run water through the system to flush it. Periodically you can run white vinegar through to clean the whole thing (a good thing to do every once in awhile even if you don't make the PME).
