Place the cabbage in a large bowl. Add 1 teaspoon salt, and use your hands to massage the cabbage until it begins to soften and release liquid, about 3 minutes. Add the remaining vegetables and spices and another 1 teaspoon salt to the cabbage. Wear gloves to prevent staining hands. Continue to massage the cabbage mixture, crunching and squeezing the vegetables and spices until well combined, about 3 minutes more. Taste the mixture and, if desired, add the final 1 teaspoon salt. (TIP: You want the mixture to be salty but not quite as salty as seawater.)
