You will need a cup or so of dried orange/tangerine peels
1/4 cup green coffee beans
1/2 cup oatmeal
1 cone shaped coffee filter
food processor or strong blender
Gather everything up. I used a mixture of tangerine, navel orange and blood orange peels. I save them all so I have quite the basket of dried peels. I also roast my own coffee, so I have tons of beans. If you don't happen to have those, check with a local roaster. They will likely sell you a small amount for not too much money. Today most towns have an artisanal coffee roaster, so just google away and you 'll find someone. You an also order them from many online sources, but that's more money unless you just really want a pound or more.
Put all the ingredients into a food processor or blender. Grind away. The coffee beans are tough on a blender so I tend to take a few seconds off in between pulses. I don't want to burn out my Ninja. I don't go for smooth texture. That's almost impossible with green coffee beans because they are so tough and they also tend to have quite a bit of moisture in them so they don't go to powder.
Put 3 tablespoons or so into your filter
Fold the top over once and then fold the sides in
Fold the top over again. This will help keep all the stuff INSIDE the filter and not all over the inside of your tub.
Secure it closed with a staple or even a hair tie if that's what you have. Just make sure it won't come open when it's floating around in the tub.
Toss into the bath when you are filling it and then relax and enjoy.
The dry mix can also be added to a gentle liquid soap for a body scrub but I wouldn't use it on the face. The orange oil can be pretty intense if you get too much on sensitive skin. It's great for removing gunk off of your hands though.
