Aleppo soap has a reputation going back centuries
Always wear protective goggles, gloves, long sleeved clothing and closed shoes when handling caustic materials.
Measure the water into a heatproof container. Measure the caustic soda carefully into a separate container.
Slowly pour the caustic soda into the water while stirring slowly and consistently until all the granules are fully dissolved. Place the now hot and fumy container somewhere safe to cool. Do not breath the fumes that are coming off the container.
Allow to cool to 40ºC.
In the meantime.....
Prepare your moulds.
Weigh the oils into a medium sized saucepan and heat gently until the contents is around 40ºC, being the same temperature as your lye.
Pour lye mix carefully into oils and stir well. Using a stick blender or large plastic spoon blend until light trace (when the batter has thickened enough to be able to drizzle raised soap mix onto the surface of your mix with your stirring implement)
Carefully pour your soap into your waiting moulds. Cover or insulate as required and leave to sit for 24-48 hours before unmoulding and cutting if required.
Allow to cure for a minimum of 6 weeks with adequate air circulation. ( With this soap, longer is better due to the high olive content.)
Enjoy your amazing soap.
