Turn Used Coffee Grounds into Coffee Granitas

You've brewed your coffee and enjoyed it, but that doesn't mean your java experience ends there and you have to toss the spent grounds in the trash. The Food Network suggests creating another drink from them: cool coffee granitas.
Steep the grounds again and add some sugar and salt, then freeze to make a frozen coffee drink. The extra steeping, freezing, and added condiments make the granitas taste as good as if you used fresh-brewed coffee for this process—plus you get more mileage for those expensive coffee beans.
Jonathan Kallini, patry chef at Atlanta's Floataway Cafe, offers this clever coffee reuse on the Food Network, which showcases a few more ways to use up kitchen waste (apple cores and corn silk, for example) in the link below.
(And if you don't want to re-steep your coffee for drinking, you can always use those old coffee grounds for cleaning up a fireplace, cleaning dishes and killing fleas, touching up wood furniture dings, and more.)
