Fermentation warning:

Fermented cauliflower is pretty awful.

Cauliflower is tasty prepared in oh so many ways, but fermentation is not one of them.

It gives you a sharp taste in the back of your mouth, just like you taste when you're in the middle of vomiting.

So, unless you like that, just don't go and ferment cauliflower, spend your time fermenting something else.
