My favorite dish is borsch. As far as I'm conerned, everyone, who lives in Ukraine, is keen on borsch.
It's absolutely tasty dish. The first time I fell in love with this dish was when I was a child and used to eat it almost every day. It's so appetizing that I even learned how to cook this dish myself. I tried home-made borsch at my friend's house and in some restaurants with Ukrainian national cuisine.
To be more precise, it's a beetroot soup, with beetroot as its main ingredient but also including potatos, onions, carrots, cabbage, meat (pork or beef), and tomato paste. Several other ingredients may also be added. Sourcream on top is recommended.
To conclude, everyone has his favorite dish, but for me the savoriest one is borsch!
