1-2 tsp seasonings of you choice i.e. mustard seed, fennel seed, caraway, garlic, dill, etc.
Directions:
Core and quarter your cabbage. Slice crosswise as thinly as you can.
Combine cabbage, sea salt, and spices in a large bowl. Mix until well combined, and then gently crush with your hands until the mixture starts to release liquid (about five minutes).
Pack the sauerkraut tightly into a clean glass jar so that the liquid rises to the top. Make sure the sauerkraut stays below the surface of the brine in order to prevent spoilage.
Check the jar every day to make sure the sauerkraut is still submerged. Scrape away any scum you notice. The sauerkraut should be ready to taste after three days.
