What Is Sauerkraut and How Is It Made?

Sauerkraut is a tangy fermented food made from shredded cabbage. 2,000 years ago, it was a way to keep vegetables fresh and safe to eat before refrigerators existed.

To make sauerkraut, you start by shredding cabbage and mixing it with salt. Lactic acid bacteria on the cabbage leaves eat the sugars, making lactic acid. This acid helps preserve the cabbage and grows good bacteria. Homemade sauerkraut keeps these live bacteria, unlike store-bought versions.

• Shred cabbage thinly to release its natural juices.
• Mix with salt to draw out moisture, creating brine.
• Pack into a clean jar, pressing until the cabbage is submerged under liquid to prevent mold.
• Cover with a cabbage leaf or lid, and let ferment at room temperature for 1-4 weeks.
• Once ready, refrigerate to slow fermentation and extend shelf life.

Traditional fermentation uses natural bacteria, while modern methods use controlled environments. Homemade sauerkraut lasts months when stored properly. It's not just preserved cabbage but a food full of probiotics and nutrients, thanks to fermentation.
