I got the idea from Martha Stewart's scented sugars. She used "aromatic edibles" layered sugar to add some flavor and scent. (Please don't eat these bath salts.) So I tried the same thing with some Epson salt and citrus zest. It worked like a charm!
These make a great gift paired with a pumice stone and are really easy to put together.
You need Epson salts, a citrus fruit and a glass jar.
1. Zest some citrus. I used the zest from half a grapefruit for 2 cups salts.
2. Layer the zest and Epson salts in a glass jar.
3. Let the jar sit with the lid off for a few days until the zest has dried out.
4. Put the lid back on the jar and shake it up. Done!
You could use lemon, lime, grapefruit or even orange zest. It would be fun to experiment with a combination of zests. Try it out!
