What is "wodzionka"

Wodzionka ( Silesian: wodźůnka) or brotzupa is a Silesian soup made from stale bread, fat and water or milk. Traditionally, wodzionka is prepared by soaking two- to three-day-old stale bread in water or broth and adding garlic, bay leaves, pepper and other seasonings, fried bacon, and lard or butter. It was reportedly served in late autumn and winter, when cows had less milk.
