So prevention only need to be able to appropriately loosen the cap some, do not completely tighten, so as not to lead to bottles filled with sauerkraut to burst the danger.
The practice of glass bottle pickles is very simple, first buy back a cabbage, and then remove the root, set aside the cabbage to wash and dry the water. Cut the cabbage into julienne, so that pickling faster. Put it into a pot and sprinkle salt and rub it slowly until the cabbage.
Put the kneaded cabbage into a glass jar without water and oil, be careful not to have oil and water, or the pickles are very easy to spoil. Seal the jar after filling and leave it for about a month.
