The recipes say to use fresh coffee grounds and fresh espresso to make the lye, but as we don't drink coffee, and this was just for washing hands, I wanted to use waste coffee grounds instead. We got some from a friend of a friend with a cafe and I dried them in the woodstove. I used packets of instant coffee that I keep around in case someone wants a coffee.
I decided to use half tallow, quarter coconut oil and quarter olive oil for this recipe as the coconut oil adds more suds and that seemed appropriate for a soap that would be used to clean hands. The recipes also suggested that the coffee would remove other odours. I wondered what it would smell like, so I didn't use an essential oil for this first batch.
Coffee soap recipe
250g olive oil
250g coconut oil
300-330g coffee (cooled)
The soap doesn't smell like coffee, so next time I would use an essential oil like tea tree or eucalyptus. I quite like the colour from the coffee, and it does seem to work at cleaning my hands after gardening.
