I'm going to start a batch tomorrow with fresh milled flour. I'll let you know how it turns out.
*know* PP (#5) plastic containers are food safe, and (generally) non-leaching. But I could not get myself to purchase the 2.5 gallon squarish PP container today. I walked out with a 2 gallon glass jar.
I will need to move a shelf in my fridge to get it to fit, but I'm o.k. with that.
