Once you've zested the lemon, sprinkle the zest into the bottom of the soap mold.
Chop the glycerin melt and pour soap into cubes, then melt them in a double boiler.
Once the soap base is melted, combine the honey and essential oils until everything is well combined.
Immediately pour the honey lemon soap mixture into your soap molds over the lemon zest. Allow the soap bars to cool for at least an hour until they are completely cool and hardened.
Gently pop each honey lemon soap bar out of its mold.
