As requested in another thread, this is how I make my sauerkraut.
Start with the freshest cabbage possible. Remove the outter few layers of leaves. Remove the cores and shred the cabbage up. The finer you shred it, the more poingant your kraut will be.
I ferment my kraut in a hand fashioned 3 gallon stoneware crock. It can fit up to 8 pounds of cabbage. I do 5 lb. batches, and yield about 6 pints of finished sauerkraut. This is a good batch size for my house hold consumption.
Ok wash out your fermentation vessel, but don't santitize it cause you'll kill the precious lactobaccilii. Mix your shredded cabbage with about 1 tbs. of salt per pound of cabbage. DO NOT USE iodized salt. I use pickling salt. Kosher salt is good to cause it's not iodized. Put the salted cabbage in your crock and let it set for a half hour or till it begins to weep. Now get something heavy to pound the cabbage. I use a 2x4 piece of wood about 4 feet long. Procede to stomp the wits out of the cabbage, smashing the liquid from it. Do this until you have enough brine to cover the cabbage. If needs be you can make a brine from about 1.5 tbs of salt per liter of water to get enough to cover the cabbage.
Now we need to weigh it down. This is to ensure the cabbage stays submerged in the brine. Keeps it from rotting. Traditional methods used a plate or wooden disk with a rock on it. I used a large plastic bag filled with a gallon for brine, tyed in a knot at the top. Ths bag acts a weight and a air lock. I put brine in it just in case it leaks, won't ruin your kraut.
Set it aside and wait. Optimal temperatures are about 70F degrees, but anywhere from 60 to 80 will be fine. The warm it is the faster it will ferment. I like to let mine set for 6 to 8 weeks cause I like a very sour sauerkraut. I've had kraut finish out in 3 weeks and take as long as 3 months. Let you own taste be your judge.
The first week or so you'll want to remove your weight and clean off the bloom from the sides of your fermentor. Bloom is a kind of foamy scum that may or may not appear.
When the kraut is done, boil can it. You can pressure can it, but since it is a very high acid food boil canning will be fine. Like wise you can store it fresh in the fridge for a month or two.
This is very easy...give it a try. Your taste buds will thanks you
