Polish Żurek is a soup traditionally prepared for Easter. In some Polish families White Borsch is cooked instead of Żurek, the difference is Kvas/ sourdough that is used. For Żurek- rye sourdough, for Borsch – wheat sour starter.
If you plan to cook traditional Polish Sour Soup Żurek, you need a rye sourdough. You can buy one in Polish store or – I encourage you to- make one at home. It takes few days for the fermentation to make it job, so few days before making Żurek, follow these instructions: http://cookinpolish.com/sourdough-for-sour-soup-zakwas-na-zurek/.
