A few years ago I made about 75 bags of coffee mixes (each was about 6 cups) for our Holiday Boutique. Talk about quick sellers!!!
I can't find my recipes, but here's a site that has quite a few. Something I did notice
was that if you use brown sugar in the mix, you get a good "caramel" flavor. Also,
if you like an orange coffee or raspberry cocoa, powdered jell-o is a great add-in!
Also, powdered vanilla drink mix is a great addition to almost everything!
