There's a soup that I grew up with, which I generally recognized immediately by its bright orange color and distinctively tart aroma. In Chinese, it's called 罗宋汤 ("luo song tang"), which I just realized is the Chinese pronounciation of "Russian" soup. Apparently, after some brief research, it turns out that this Russian inspired soup actually has a name, and it's called borscht. Borscht is traditionally a deep red color because of the beetroots in the soup, but In my family's case, we make a variation of it called orange borscht, which gets its color from the use of tomato paste. Borscht is mainly a vegetable soup, made in our household with potatoes, carrots, cabbage, and onions, with some Chinese sausage as well. The Polish version of the soup usually uses Kielbasa instead, but like I said, this is Chinese style borscht :) I suppose China being so close to Russia means that there is bound to be cultural exchange within the cuisine. My mom likes to make things easy by using ketchup in this soup instead of real tomato paste, and I think the taste is great either way. It's tart but balanced out by the sweetness of the cabbage, and it's always hot and hearty, great for a cold winter's day.
