Mountain Mint Foot Soap

Olive oil is infused with dried mountain mint
Take about 1 tablespoon of your measured liquid oils and make a smooth slurry with the 10 g Rhassoul. Mix that back into the entire pot of oils before adding the lye.
Mix the 5 g activated charcoal with roughly 1 tablespoon of your measured recipe oil until completely smooth. Set this little black slurry aside to add to 25-30% of the batter at stable emulsion.
After adding your lye solution to the main oils, stick-blend with short pulses alternating with hand stirring. Stop at stable emulsion. Don't wait for visible trace.
Immediately pour about 25–30% of the batter into a separate container. Hand-stir the prepared charcoal slurry into the smaller portion. Don't stick-blend it unless absolutely necessary. Alternate pours of the warm Rhassoul/tan batter and charcoal batter, then give it one or two gentle passes with a skewer. Don't over-swirl or you'll end up with gray soap instead of a distinct charcoal swirl.
Infused olive oil → melt/combine oils → Rhassoul → EO blend → lye → blend only to emulsion → split 25–30% → charcoal into small portion → swirl → pour.
