To make this Coffee Soap recipe -
- Start with a Basic Soap Recipe.
- Substitute double strength coffee for your water in the lye-water solution. (Be sure you understand how to make a lye solution with liquids other than water.
- At trace, add in 1-2 tsp. of the used coffee grounds for every pound of soap in your recipe.
- You can add a coffee fragrance if you like, though the coffee scent will come through lightly even without it. I've also made it with a bit of peppermint essential oil as well - a lovely combination.
