She posted it with photos of her instructions and modifications as it was written with the implication that you just knew how to do it. I guess they did back then. Anyway, I just had to try it. And if this works like it is supposed to, I will never have to buy those little packets of yeast again! Woo Hoo! Sounded like a frugal idea to me! So this is how mine played out!
First, the recipe!
Cooked potatoes, sugar, yeast and salt and ground ginger. Ginger? Why? I have no idea, but I added it per the recipe anyway. She explained a bit about yeast in her blog. All yeast whether it comes from a package (Fleishmans) or homemade, comes from wild micro organisms from the air. The original recipe called for 3 cakes of yeast, but then, you use your homemade yeast to make you own new yeast, forever if you want to and never buy it, ever again! Add warm potato water, (that the potatoes were cooked in) cooled to barely warm.
Cover and set aside to rise till bubbly.
Meanwhile, as the yeast is rising, dry a couple of cups of cornmeal in a warm oven.
When the yeast is ready, start adding the cooled corn meal,
until it is stiff enough that you can roll it out like pie crust, about 1/8 inch thick.
Allow to dry, crumbling it up with your fingers or a fork several times as it dries. I think mine could have used a bit more cornmeal as it was still a little sticky.
When it was dry enough, I put it in the Magic Bullet and blended it into a coarse powder. (this was my own modification). As soon as I had some ready to use, I used her bread recipe that is a heirloom recipe from her grandmother and greatgrandmother,
