Suzanne, perhaps this might help. I found this in google.
Salt risen starter, Grandma's Stinky Bread!!!
My dear departed Grandma Gert used 2 old potatoes, old with large developed eyes, not moldy. Peel and cut them up about the same size as raw fries. Place in a crock, cover with 2 to 3 cups boiling water, 1/4 t.
salt, 1 t. sugar, 4 T. of corn meal. Cover and place in the oven with just the pilot light on, in about 8 to 12 hours, hopefully it will get bubbly and stinky.
Her recipe is: Heat 2 cups milk to warm, put potatoe water with milk, add 1/2 pinch salt, 1/2 t. soda and enough flour to make a spongy dough, let rise. After rise, add enough flour for a good workable bread dough,
shape into loafs, rise again in pan, then bake at 350 F. for approx. 1 hour.
