Over at Brooklynometry, there’s a recipe for homemade laundry soap. Here’s an excerpt from her post:

I made a batch of homemade laundry soap Wednesday night, this is my big big fun. I didn’t have any Zote laundry bar soap, so I used the bar of Octagon I got from Key Food. Octagon, the name makes me happy. Is there a diagnosis for that?

I grated half the bar of soap. Once I start grating soap, it’s a little hard to stop. It makes me wonder what it would like to be a tallow renderer, like Benjamin Franklin’s father.
