We have some fermenting veggies sitting on our counter, and it is pretty convenient that, in this case at least, the jars are very colorful and pretty! We started our inaugural batches of sauerkraut and kimchi last weekend, and they are tasting pretty good so far. We were kinda nervous to taste them for the first time. Knowing that you are basically growing tiny organisms in your food, and then eating them, is a little weird to actually think about!
We made sauerkraut with red cabbage, since we tend to eat that more often on tacos and things. We used this recipe for the kimchi. My one suggestion would be to wear gloves or something if you have sensitive skin. My hand had a burning feeling for a couple hours afterward!
