Once the batter came to trace, I coloured approximately one third with titanium and coloured the remainder with cocoa powder, made into a paste with a bit of safflower oil. Again, I used a hanger swirl to make it look like the foam in a glass of dark beer.
I'm much happier with this batch which, incidentally, is scented with a blend of cedarwood, patchouli, and peppermint (1 part each of the cedar and peppermint, 3 parts of patchouli).
70% Olive Oil pomace
30% Coconut Oil
5% Superfat with a lye concentration of 38%, a ratio of 1.6316:1, water:lye
I think this recipe is one I will be going to time and time again. It works, it's a nice hard soap and it's easy to modify.
