Kimchi
Ginger Beer
While we've been making our own raw sauerkraut for a while, we recently picked up "Mastering Fermentation" by Mary Karlin and have been making a vegan version of Kimchi and Ginger Beer from the book -- with great success.
On the right is the ginger "bug" used to start the process -- we've only had one slight "blowout" with the ginger beer over carbonating, but overall they've turned out great!
