I've bought Bubbies pickles and sauerkraut before and enjoy the preservative free/sugar free preservation and very sharp taste. The ingredient list is typically: veggie, seasoning(s) (if any), Artesian well water, salt.
Do these products count as legitimate fermented foods with probiotic benefits?
Here's an answer I found regarding which of their products are raw and fermented: http://herbangardener.com/2010/06/22/are-bubbies-products-raw/
I've wondered that, too, and believe in the health benefits of naturally fermented foods, so I've decided to make my own using this fermentation crock. First batch will be done in about a week. Then on to kimchi, fermented pickles, whatever my mind conceives!
