Yesterday I was somewhere with hard water, and the lather wasn’t very slick. I hypothesized that I had added too much water. Today I’m somewhere with soft water, so the only testing I can do is to see if this soap works well when made slightly pasty. Now that I know it does work when pasty, the next time I’m somewhere with hard water, I can continue my test.

… assuming I pack the same soap next time. Not likely!
