Step one: Cut goat’s milk soap base into cubes and microwave in 30 second intervals. This recipe makes 3 bars of soap. S2: Melt soap for about a minute. Add another 15-30 seconds if it’s not completely melted. S3: Once soap cubes turn liquid add a few drops of the lemon essential oil and the lemon zest of 3-4 lemons; stir well. S4: Pour into soap molds and allow to harden for at least one hour. ***Update: If you decide to use the lemon zest I recommend adding a preservative.
