In the Kitchen : Freshen Up Old Coffee

Everyday you wake up and go through your routine, which always includes buying a coffee, but you never find time to drink it and once it's cold, it's bitter not worth drinking, right?

Try adding a few grains of salt and then heating it in the microwave. You just brought your coffee back from the dead.

When coffee cools down it gets stale and bitter. The salt reduces the bitter taste allowing the original aroma of the coffee to revive when it's nuked.
