I'm continually adding things to my Culinary Goals. Recently I've added:
1. Villi - Read about this in 'Art of Fermentation' by Sandor Ellix Katz then saw the post and corresponding podcast on the subject.
2. Old Water - I find this concept intriguing. Heard about it a few years ago (2008 maybe) and it's been on my mind ever since. Here is a nice blog post that explains the concept.
3. Kefir - Since getting into Kombucha brewing I'm interested in the idea of Kefir.
4. Homemade Vinegar
5. And finally something not fermented, Black Pepper Tofu!
