The fermentation process is like a superpower that helps preserve food, and sauerkraut is a great example of this. When you ferment cabbage with salt and other ingredients, you create an environment that's rich in probiotics and other beneficial compounds. This is why sauerkraut can last for several months in the fridge, as long as it's stored properly.
But, even with its superpower-like properties, sauerkraut can still go bad if it's not stored correctly. If you notice any signs of mold, slime, or an off smell, it's time to say goodbye to your sauerkraut. It's like when you're on a road trip and you notice that your car is making a weird noise - you know it's time to pull over and take a look!
