Borscht  is a soup of Ukrainianorigin that is popular in many Eastern and Central European countries. In most of these countries, it is made with beetroot as the main ingredient, giving it a deep reddish-purple color. In some countries, tomato is used as the main ingredient, while beetroot acts as a secondary ingredient. Other, non-beet varieties also exist, such as the tomato paste-based orange borscht and green borscht (sorrel soup).
