DOUBLE BUTTER SOAP
Recipe Instructions
- Gather all of your equipment and ingredients.
- Weigh the lard and oils into a pan. Remove from heat.
- In a small glass bowl or pyrex dish, weigh the lye while wearing safety glasses and gloves.
- In a ventilated space, slowly sprinkle the lye into the container with the ice cubes while stirring until you have added all of the lye. Continue stirring until the lye is fully dissolved. Set aside in a safe place where it won’t get spilled.
- Take the temperature of the mixed oils and the temperature of the lye mixture. You will want them to be about the same temperature, in the 90-110F range. (Or that when they are combined, the average temperature will be in that range.)
- Slowly pour the oils into the lye mixture and stir well with the silicone spatula.
- After you have reached trace, use the immersion blender to fully combine the essential oil.
- Pour the batter into your soap mold.
- Cover the mold with plastic wrap and set in a cool place for 48 hours or until the soap is hard enough to remove from the molds. (When making milk soaps, I refrigerate the soap in the molds during the saponification process to ensure it doesn’t overheat and turn the soap brown.)
