Sauerkraut is made by letting fresh cabbage sit in salted water until it ferments, giving it both a sour taste and a distinctive character all its own. The beneficial bacteria that develop during fermentation make it not just flavourful but also nutritionally rich.
What does fermentation add?
As cabbage ferments, the sugar inside it is converted into lactic acid by beneficial bacteria; this process gives sauerkraut both its sour taste and its probiotic content. Probiotics are live microorganisms thought to support a balanced gut environment.
The longer the fermentation, the more sour the cabbage becomes; a short ferment gives a milder flavour, while a longer one develops a sharper, more intense character.
What is its nutritional value?
Sauerkraut is rich in vitamin C, though some of that vitamin content can be lost during fermentation. Even so, compared to fresh cabbage, its probiotic content offers a different kind of contribution to digestion.
Its salt content is worth keeping in mind too; the salt needed for fermentation makes sauerkraut a fairly high-sodium food, so anyone watching their blood pressure may want to keep portions modest.
Which dishes does it pair well with?
Sauerkraut works especially well alongside rich dishes like kavurma or fried food; its sourness lightens the heaviness of an oily meal. It is also a common addition next to grilled meat.
Added to sandwiches and toasties, sauerkraut also makes a difference in both texture and flavour; its crunch creates a contrast against softer sandwich fillings.
How should it be stored at home?
Homemade sauerkraut should be kept in its own brine, in a covered container, in the fridge; stored this way, it can stay fresh for weeks. A white film sometimes forms on top, which is normal and can be strained off before serving.
The brine level in the jar should never be allowed to run low; cabbage left without brine and exposed to air risks spoiling and can quickly become unusable.
There are also differences between homemade sauerkraut and the kind sold in shops; some store-bought jars are made with vinegar instead of true fermentation, which means they carry no probiotic content. Genuinely fermented sauerkraut usually notes something like “live cultures” on the label.
Adding spices such as cumin or bay leaf to sauerkraut can bring extra flavour without disrupting fermentation; these go into the salted water along with the cabbage and work their way into the flavour as it ferments. Red cabbage makes a version with a deeper colour and a more intense taste as well.
Eating sauerkraut without heating it matters for keeping its probiotic content intact; stirred into a hot dish, it can lose some of its beneficial bacteria on contact with high heat. That is why fermented sauerkraut is usually served cold or added to a hot dish right at the very end.
