Once the coffee grounds are completely dry, I store them in a quart jar.
|Here is a mason jar with my "dehydrated" coffee grounds.|
How can they be used? Well, we use them when we go camping. A camp percolator will cook these grounds up nicely. It tastes nice and strong so there is no reason to just throw them away. Besides, if "crap" ever does hit the fan, you'll appreciate any kind of coffee whether it is "seconds" or not. :-) Another way to use them is on your garden. It really helps the soil by adding nitrogen to the soil so in March or so, go till some used coffee grounds in your soil. Be careful not to use too much coffee in your garden though because too much will lower your soils pH balance.
