Time for something actually available. This is S: 东北酸菜; 东北 T: 東北酸菜 (dōng běi suān cài). Dongbei (literally east-north) refers to the provinces of Heilongjiang, Jilin and Liaoning. Historically, this was known as Manchuria, a name now avoided as it reminds people of Japan's brutal occupation of China from 1931 to 1945.
酸菜 (酸菜) is pickled vegetables, particularly Chinese cabbage, as here. It is often translated as 'sauerkraut' which it closely resembles. Ingredients listed are cabbage, water, salt and preservatives. (sodium dehydroacetate and potassium sorbate).
The sauerkraut is used in a number of dishes including the following, translated by my cell phone app, as I'm too lazy and these translations more 'interesting' than mine!
It can also be eaten straight from the pack. I add it to congee.
Expect to pay around $1 for 500 grams here in China.
