Polish Christmas Borscht – beetroots leaven recipe

beets leaven recipe
Polish christmas borscht

When you think of Eastern Europe cuisine you think borsch (also spelled borscht) is the flagship soup. What is borscht? How do you make it and what is so special about a beets soup? Why do Poles serve it on almost every occasion? What is the secret behind making beets delicious and how many types of borsch can you get in Polish kitchen?

There are few different kinds of Polish borscht;  sometimes borscht is thick with pieces of beet and shreds of beef, sometimes the soup blushes with sour cream, and other times it served crystal clear. I dare to say that you just can’t cook Polish food without simmering a pot of borscht. The Christmas borscht served in Poland is clear, based on beets leaven and served over a portion of Uszka.

What is borscht?

If you think that borscht is the same what a beets soup is, you are mistaken. Borscht is always based on sourdough. In the Polish kitchen, you make sourdough by adding: water from pickles or sauerkraut, beetroots leaven, rye for żurek, lemon juice, gooseberry, redcurrant or cranberry. If you want to prepare real borscht you may think few days in advance since it needs time.
