Earlier, there was a thread on fermented foods. I ran across this reference
to fermented wheat bran
and wondered how it is made and in which countries it is in common use and
how used:
ROMANIA
Ciorba de perisoare: Soup with meatballs. The soup can be sour - made with fermented wheat bran, lemon juice, or the
liquid from sauerkraut. It also contains vegetables such as carrot, parsnip and chopped tomatoes, and can be flavoured
with celeriac, lovage and dill.
