Given this paragraph, where did the German dish sauerkraut originate from?

Context: Although "sauerkraut" is from a German word, the dish did not originate in Germany. Some claim fermenting cabbage suan cai was already practised in the days of the building of the Great Wall of China and that the practice was likely transmitted from China to Europe by the Tartars. However, the Romans, as previously noted, pickled forms of cabbage, and were the more likely source of modern-day sauerkraut It then took root in Central and Eastern European cuisines, but also in other countries including the Netherlands, where it is known as zuurkool, and France, where the name became choucroute. The English name is borrowed from German where it means "sour cabbage". The names in Slavic and other Central and Eastern European languages have similar meanings with the German word: "fermented cabbage" or "sour cabbage".

Answer: The Romans are believed to be the most likely origin of the German dish called sauerkraut.
