I like the pictures and it does a good job of explaining the steps in making fermented foods. One note, when I make beer, wine and other fermented things cleaning is the first step. I read in a beer
magazine once " You can sanitize dog
poop but that does not make it clean." Next I sanitize everything that will come in contact with the ingredients. And I will admit sometimes I forgot to sanitize a fermenter but the beer turned out good.
When my gut is not in a good place, miso does help me out. And sauerkraut is good with potatoes. Kimchi is good really if you like hot things. Last tempeh, I need to make some!
