Clean vegetables to wash dirt off. Remove any dark green tough outer leaves from cabbage and compost or use for another purpose.
Slice a cabbage head in half lengthwise, so that stem keeps each half together. Shred each half into ¼”/8mm ribbons using v-slicer, mandoline, or chef’s knife.
Sprinkle salt evenly throughout bowl.
Squeeze or pound the mixture with clean hands or a kraut pounder to break the cell walls and encourage more water to come out of vegetables.
Remove top from pepper. To increase spiciness, leave seeds and membrane in. Otherwise carefully slice the membrane out. Dice pepper and add to mixing bowl.
Add spice powders to bowl. Mix thoroughly with tongs or clean hands.
Add veg to a gallon-sized or larger glass jar or ceramic crock, or about 2 quart-sized wide mouth mason or other canning jars. Make sure to get every last drop of brine that formed in bowl into the container(s)!
Pack down contents so that surface is even and flat.
