Cook's tip
Zakwas varies in sourness, so add three quarters first and taste before adding the rest. If you can't find white sausage, use smoked sausage and simmer it only 10 minutes in step 3. Leftover żurek is even better the next day.
Cooking it at camp
It cooks in a single pot on a camp stove as written. Boil the eggs at home; white sausage is raw, so keep it cold in the cooler. You shake the zakwas bottle, so check the lid is tight.
