depending on the warmth of your kitchen, sauerkraut takes about a week to 10 days to sour fully.
It does involve cutting it thin, mixing with salt, packing tightly into a crock or other container, weighing it down to keep the ***** below the liquid that will form, daily maintenance and then canning it.
There is a way to make it directly in the jar but I have never done that.
And no you do not need to use a pressure cooker.
i just made 10 pints last fall and used to make up to 100 quarts every other year and I have never owned a pressure cooker.
You also do not have to cook it and can keep it, in small amounts, in the crock in your fridge, much like refrigerator pickles or kimchi, which is basically spicy hot sauerkraut.
參考: made my own for years.
