Russian recipe?
Sigh. I have to remember I am not making fun of people who did it because they were starving, I am doing it because some kind of fruitcake of a baker thinks this is an interesting product to offer to people.
Which is a totally bizarre concept, but...there you have it!
I have read extensively on the POW experience, and recall that sawdust was used extensively by both the Nazis and the Japanese to “feed” their POW’s.
I expect at some point in the war, both the German and Japanese populations themselves were eating sawdust infused bread.
One of the things that is apparent to me in my extensive readings is that the power of starvation will make people eat nearly anything including other people.
I just cannot wrap my head around why some baker thought this is a good product for his customers.
