Marseille Soap Recipe

[dcotton1]

Looking for a recipe for traditional Marseille soap. I have found several for Castille soap but not Marseille. Thanks in advance

Pretty sure traditional Marseille can only be called that if its made in Marseille France the traditional way of boiling in salt water with local made alkali.
I've never seen a exact recipe and even if you found one, continously boiling for multiple days could be tricky in a home setting.

What obsidian said. There really isn’t a way to make a true Marseille soap for us home soapers unless you’ve got the time and equipment.
