The most popular taste of life in the city is that of the old sour foods in the northeast, and it's coming out of the mouth. I don't get tired of eating. Green, authentic, not the sour sauce from the city supermarket, not the smell, hard to swallow! In the past, Northeasters had two things in their homes: a sour cask and a big stone for pickled vegetables. The sour fermented fermented with large cabbage is salty, tastes soft, colourful, fragrance, appetizers, and ablaze; it not only enhances appetite, helps digestion, but also promotes human absorption of iron. Acid fermentation is the result of lactating acids from sugar in the cactus decomposition. Lactate is an organic acid which, when absorbed by the human body, enhances appetite and digestion, while cabbage becomes acid and its nutrient content is not easily lost。
