hapankaat
Hapankaat is a traditional Finnish dish, a type of sourdough rye bread soup. It is typically made with water, rye flour, and a sourdough starter. The ingredients are simmered together until the soup thickens. Often, stale rye bread is added to the mixture, which contributes to the sour flavor and characteristic texture.
The preparation of hapankaat involves a fermentation process, as it relies on sourdough for leavening and flavor.
Historically, hapankaat was a common and economical meal in rural Finland, particularly in the eastern parts
