There is a ton of free information out there, too. A lot of Weston A. Price diet followers are very experienced in fermenting, and many of them have fairly decent blogs with many recipes. I also enjoy the Cultures for Health website. They
sell cultures for yogurt, etc. but they also have a ton of recipes and information on all types of fermented foods.
Kind of off topic, I was speaking with an 18-year old Korean friend the other day, and she was explaining that Kimchi is "so we can have vegetables during the winter," as if it is a completely foundational part of her understanding of food. I am so glad her family and culture has retained that
common sense! If only more American teenagers felt the same way about seasonality and good fermented foods!
