Mmmmm… Sauerkraut! It tastes delicious, whether cold or warm, pure or as a side dish. With sauerkraut you not only delight your palate, but also your intestines, because sauerkraut contains valuable probiotics. These are living bacteria and fungi that do a lot of good for your intestines. If they are present in sufficient quantities, your intestinal flora is in balance and your immune system is full of power. Sauerkraut is good for your gut, it contains many valuable probiotics, namely lactic acid bacteria. However, you can only find these in fresh sauerkraut from the health food store or the weekly market. Sauerkraut from the supermarket is strongly heated in order to keep it as long as possible. However, the heat means death for the valuable lactic acid bacteria. With the right tools and a little patience, you can easily make yourself a healthy, delicious sauerkraut.
How the valuable lactic acid bacteria are created
The process is called fermentation or fermentation process. The bacteria multiply all by themselves. Thousands of years ago, people used this method to preserve their vegetables longer. In fact, it is believed that the first sauerkraut was produced by the Chinese. Crazy, right? After all, sauerkraut is known all over the world today as a typical German dish. It’s not for nothing that the Germans are called the “Krauts”.
The base of sauerkraut is very finely chopped white cabbage mixed with salt. By nature, cabbage carries a number of bacteria. In order for them to do their job, the cabbage must be put under a lot of pressure. This destroys the cell walls and allows water and air to escape.
This is how the fermentation process begins: the bacteria consume the oxygen that is still present and produce lactic acid in the process. The lactic acid also gives the white cabbage its typical sour taste. Harmful bacteria and fungi do not feel comfortable in this acidic environment. Their development is suppressed, which among other things prevents the formation of mould.
For the production of sauerkraut a so-called fermentation pot made of clay is often used. This exerts the pressure on the cabbage necessary for fermentation. But even without this pot you can easily make sauerkraut yourself.
And here come the two recipes:
Sauerkraut good for gut – Sauerkraut in the fermenting pot
In principle, the following rule applies: for 1 kilo of cabbage you need 20 grams of salt. So you can vary the amount. For a fermenting pot with a capacity of 10 litres you need
- 8 kg white cabbage (preferably unsprayed from the organic food store)
- 160 grams salt juniper
- caraway or bay leaves as desired
You should not wash the cabbage, valuable bacteria are lost in the process.
Remove only the outer leaves and cut the cabbage into large pieces. Remove the stalk and cut everything into fine strips. You can also use a slicer or the food processor.
Put a layer of cabbage in the pot, cover with a handful of salt and mix everything well. Use a wooden tamper and crush the cabbage until it gives off liquid. Then put another layer of cabbage and salt in the pot and pound everything again. Repeat this process with the rest of the cabbage and salt.
Then place a clean cabbage leaf in the pot and place the clean and preferably sterile stone weights on top. The weights ensure that the cabbage always remains covered with liquid.
Close the fermenting pot with the lid and fill some water into the channel provided. The water ensures that the gases produced can escape to the outside and at the same time prevents air from getting into the pot from outside.
Now you have to wait 6 to 8 days until the fermentation process is completed.
This works best at room temperature and only if you keep the pot closed.
Sauerkraut without fermenting pot
You need a few large glasses with screw cap or the classic preserving jars. Additionally you need one very small glass per jar, which you put on top of the cabbage to weigh it down.
Of course you can vary the amount of ingredients again. Here is a variant for about 2 kilos of sauerkraut:
- 2 kilograms white cabbage (preferably unsprayed from the organic food store)
- 40 grams salt
- any spices you like
Prepare the cabbage as for the fermentation pot (see above). Mix the finely chopped cabbage with salt in a large bowl and pound everything with a wooden mallet until water comes out. Fill the cabbage into a glass, press everything firmly so that the cabbage is always surrounded by liquid. Finally, place a clean leaf of cabbage on top. Press the small glass onto the cabbage leaf. Make sure that the cabbage is completely covered with liquid. Close the jar and store it at room temperature for 2-3 days.
Then place it in a cooler, darker place like the pantry for about 20 days.
Enjoy your meal!
