Tangy, crunchy, and alive with probiotic goodness, homemade sauerkraut is one of those kitchen projects that feels almost magical for how little effort it actually takes. The entire ingredient list is just two items — green cabbage and non-iodized fine sea salt — which is exactly what makes this recipe such a reliable fit for anyone managing iodine intake. Iodized table salt is the sneaky culprit in so many otherwise simple recipes, but swapping it for non-iodized sea salt here keeps everything clean and compliant without changing the flavor or the fermentation process at all. You massage the salt into the shredded cabbage until it releases its own brine, then pack it into a jar and let time do the rest. No vinegar, no additives, no store-bought mystery ingredients to decode. After about a week at room temperature, you'll have a deeply sour, complex condiment that's genuinely better than anything in a can or pouch. It keeps beautifully in the fridge once it hits your preferred level of tang, so one small head of cabbage goes a surprisingly long way.

Peel off and set aside 1–2 large outer cabbage leaves. Quarter the cabbage, cut out the core, and slice the remaining cabbage into thin shreds about 1/8-inch thick.
Place the shredded cabbage in a large mixing bowl and sprinkle the sea salt evenly over it. Massage and squeeze the cabbage firmly with clean hands for 8–10 minutes, until it has released a significant amount of liquid and feels limp and wet — the brine should pool visibly at the bottom of the bowl.
