Weigh the cabbage and determine the salt measurement.
The amount of salt you use should come to about 1.5-2.5 percent, but no more than 3 percent, of the cabbage weight.
Transfer the cabbage to a large bowl or container, sprinkle over the salt and let sit.
Pound or massage to get all of the juices out – ideally enough so that if you pick up a handful of cabbage you’ll have dripping water flowing from a clenched fist.
Add the fennel seeds and mix thoroughly. Pack tightly into your jar or crock, add the follower, and weigh down.
Seal with your preferred system. Wait. Check.
It will keep in the fridge for up to 12 months.
