HOW LONG TO FERMENT SAUERKRAUT RECIPES

Steps:

• Thoroughly wash a large tub or bowl (we used on the size of a small washing-up bowl), then rinse with boiling water from the kettle. Make sure that your hands, and everything else coming into contact with the cabbage, are very clean. It’s wise to use a container that will comfortably fit the softened cabbage, allowing several inches of room at the top to avoid overflow.
• Shred the cabbage thinly – a food processor makes light work of this. Layer the cabbage and the salt in the tub or bowl. Massage the salt into the cabbage for 5 mins, wait 5 mins, then repeat. You should end up with a much-reduced volume of cabbage sitting in its own brine. Mix in the caraway seeds and the peppercorns.
• Cover the surface of the cabbage entirely with a sheet of cling film, then press out all the air bubbles from below. Weigh the cabbage down using a couple of heavy plates, or other weights that fit your bowl, and cover as much of the cabbage as possible. The level of the brine will rise to cover the cabbage a little. Cover the tub and leave in a dark place at a cool room temperature (about 18-20C) for at least five days. It will be ready to eat after five days, but for maximum flavour leave the cabbage to ferment for anywhere between 2-6 weeks (or until the bubbling subsides).
• Check the cabbage every day or so, releasing any gases that have built up as it ferments, giving it a stir to release the bubbles. If any scum forms, remove it, rinse the weights in boiling water and replace the cling film. You should see bubbles appearing within the cabbage, and possibly some foam on the top of the brine. It’s important to keep it at an even, cool room temperature – too cool and the ferment will take longer than you’d like, too warm and the sauerkraut may become mouldy or ferment too quickly, leading to a less than perfect result.
• The cabbage will become increasingly sour the longer it’s fermented, so taste it now and again. When you like the flavour, transfer it to smaller sterilised jars. Will keep in the fridge for up to six months.

Steps:

• Weigh the shredded cabbage (as cabbages vary in size and weight) to ensure the salt to cabbage ratio is correct. The amount of salt you use should come to about 1.5–2.5%, but no more than 3%, of the cabbage weight.
• In a large bowl, mix and massage the salt through the cabbage thoroughly, making sure to distribute the salt evenly.
• Let it sit to sweat a bit—maybe 10 minutes. This is simply to make the next step easier. This is a good time to get your vessel cleaned and to rest up for the next stage.
• With your pounder, pound quite energetically for about 5–10 minutes, until the cabbage is dripping with its own salty water when you pick up a handful. This part is important as you need this liquid—it’s your brine.
• You can also use the dough hook of a stand mixer to do the pounding part, which can speed things up somewhat. Don’t let it run for too long though, only a few minutes. Using a mixer is easy and great for people who are doing this a lot and in large batches, but it takes quite a bit of the emotional release and fun out of it.
• Next, mix in the caraway seeds (if using).
• Put the mixture into the jar, packing it down tightly as you go using the pounder. Push down well, particularly at the end to coax out any more brine. You need the brine to cover the cabbage.
• Don’t pack the cabbage all the way to the top; leave some headroom at the top of the jar to allow for a bit of growth and movement and, of course, the weight. You don’t want the liquid touching the top of the lid, as it will end up spewing out of your air-lock or up out of your lid.
• Cover with a cabbage leaf (the follower), the weight and then your chosen lid or system.
• Depending on your ferment, you can start trying it as soon as you’d like, but the less you fiddle with it in the first 2 weeks, the better. It is ready when you think it is delicious. With the right system and temperature, you can leave it to ferment for months before refrigeration.
• If you used a crock, you’ll need to decant the kraut to smaller jars before you refrigerate, unless you have a walk-in cool room, or large cellar. (Lucky you.) It will keep in the fridge for 12 months or more. Use your senses.
