A video about the making of Borodinsky bread is available. It is in
Russian and originally was on a TV show.
There are two sources:
either
http://www.proletarets.ru/files/video/ntv.mp1.mpg
or:
http://www.proletarets.ru/files/video/ntv.vcd.mpg
Obviously, they feature the Proletarets bakery, so they are on their
website.
