I just figured out my sauerkraut was coming out limp because I was using iodized salt from the grocery store this whole time. | Fermentation Station - Opinions Matter
Honestly that neighbor look is a whole mood. Tbh my first batch of pickles turned out weirdly cloudy and soft, and I was so confused. Ngl I had no idea the minerals in tap water could mess with fermentation like that. Ended up reading way too many forums at 2am about water hardness. Felt pretty silly using fancy filtered water just for pickles, but it actually worked.
Yeah, water chemistry is no joke. I ruined a batch of sauerkraut with our super hard tap water before I figured it out. Now I just keep a cheap jug of distilled water in the pantry for ferments.
