Well, I have never made them CP so I can't really tell you what the difference is, but the process is pretty simple... Just mix you lye water with your melted oil in a crockpot, stick blend to medium trace, put the lid on and cook it on low. It will rise up, make sure you have enough room! Stir every so often (it probably doesn't need to be stirred as often as I do it, like every 10 minutes, but I like to feel involved). It will go through a separation stage, just keep stirring. After it looks like something between mashed potatoes and vaseline, anywhere from 30 minutes to an hour, it is ready!
Turn off the heat, add fragrance and whatever else you want (like coconut milk mixture) and then finally your salt. Stir like crazy and put in mold ASAP!
I was so afraid that mine would harden up too quickly so I cut mine after an hour or two, it was too soon. Next time individual bars silicone mold!
That's really about it, you can do a search on hot process to get some great pics of what it is supposed to look like, and almost any recipe can be HP'd. I use a crock pot but you can also use a double boiler or the oven. Good luck!
