As far as I know any of your cp recipes can be used in hp. Just make sure you have a crock pot that is big enough for the batch you are making. I wait until the end of my cook to add anything like oatmeal, goatsmilk powder and fragrance. You use about half as much fragrance in HP so thats nice! The only thing I don't like about hp is the "marbled" effect that you get in the mold and that the top isn't nearly as pretty as cp soap. Other than that the instant usability is pretty awesome and I think that by adding the EO's after the lye is completely saponified helps maintain some of the properties of them. Good luck!
