I have been loving the shampoo bar I got at whole foods, and have been using the bar with a vinegar and water hair rinse for the last 2 months. I love the way my hair feels, and the bar gives back a bit of texture to my super-uber-straight hair that bobby pins fall out of if I stick them in any other way but from the top down unless I use half a can of hairspray on it. Anyway, I made a batch of soap last month and it came out OK - so I figured I'd make a simple shampoo bar! Searched for a recipe that required no calculations and would make a small batch in case I wrecked it or I hated it (scroll to the bottom)..... Here is what I made:
I used a junk-drawer organizer thing from Target for the mold, and it was the absolutely perfect size for the volume of soap, I lined the container with parchment paper, poured in the sludge i mean soap, let it sit overnight covered with towels so it would cool SLOWLY and not leave an unappetizing white layer on top. This morning I turned it out and cut it into one inch sections - each "bar" weighs in between 2 and 3/4 and 2 and 5/8 ounces. Now it has to sit for 3 or 4 weeks then I can give it a try!
Here is the recipe for a one pound chunk of soap. I found it at http://www.colebrothers.com/soap (if you leave off the "/soap" you end up looking at a ton of cool tape and adhesives!) where they have a bunch of smaller volume recipes designed to be made in a blender - I used a hand-held stick blender and it worked great.
