Cut your loofah into slices for your soap. Remove any seeds. Ensure it fits into the cupcake silicone mould.
Dry your loofah completely. If it is shrunken or misshapen at all, soak it beforehand to restore it to its full size again, then make sure to dry it fully.
Make your soap using my 50/50 soap recipe. At trace, add in grapefruit essential oil and blend well.
Add in your turmeric and madder root powder for a light colour. Add a little or more depending on your preference. Blend again.
Pour the soap halfway (or a little more than halfway) up your silicone cupcake mould. Place a loofah slice on top of each soap.
Let the soap sit untouched for 48 hours.
Unmold the soap. Let it cure on a wire rack for 6 weeks before using.
