I have a recipe for a REAL potato bread my father used to make in our bakery (in Germany) way back in the 1930s. The recipe is older than that. I tried it once and made a mistake because the recipe does no speify wether the poatoes are supposed to raw or cooked. So I grated them raw and the bread was a disaster.
I just bought a new potato ricer and will be experimenting later this week. The recipe is most likely from the early 1900 s. My father wrote it down like this:
10 to 15 potatoes
3 pounds of flour
20 Pfennigs worth of yeast
a small hand full of salt
enough water to make the dough just right.
Let rise once, knead lightly , shape and put into a wll greased pan and put into oven immediately.
That is it. I am thinking 15 small poatoes (very mealy ones) are about 3 lbs, same amount as flour. 2 small pckg of yeast should be plenty (since I buy yeast in bulk I am going to try 1 slightly rounded tbsp). Idon't worry about water since I do have a "feel" for when a dough is just right.
I remember the bread was one giant loaf with a dark brown crust and a bit coarser texture because of the riced potatoes. And it really tasted like poatoes and warm, with butter on it was a treat fit for a king.
I will let you know how my experiment turns out. I am trying half a recipe, just in case but am bound and deternined to perfect it.
I know US recipes call for one cup of mashed potatoes for one or two loaves of bread but one can't even taste the potatoes in that kind of bread amd that is why I want to make the old recipe.. See you towards the end of the week IF you are interested.
