Sauerkraut (sourcrout) is a very simple recipe, it only requires three ingredients: cabbage, salt, time. It also has many variations.
The Basic Recipe
The recipe requires only two basic ingredients, but the combination takes slightly more effort. To make a basic sauerkraut, finely shred some cabbage, and then toss in ~1.5% (by weight) non-iodized salt. Leave it alone for 30+ minutes while the salt pulls out water from the cabbage. Once the water is pulled out, give it a good punch 'n squeeze.
The water pulled out of the cabbage mixes with the salt and creates its own brine.
