Billäs

Billäs refers to a type of traditional Swedish rye bread. It is characterized by its dense, dark texture and distinctive sour flavor, achieved through a long fermentation process and the use of a sourdough starter. The bread is typically baked in a round, flat shape, often with a hole in the center, which aids in even baking and drying.

The primary ingredients in billäs are rye flour, water, salt, and sourdough. Some recipes may also include a small amount of yeast to ensure a consistent rise, though sourdough is the dominant leavening agent. The dough is allowed to ferment for an extended period, sometimes days, to develop its complex flavor profile. After baking, billäs is often dried further, either in a low oven or by hanging it. This drying process contributes to its long shelf life.

Billäs is traditionally served with butter and is a common accompaniment to various Swedish dishes, particularly those featuring herring, cheese, or cured meats. It is also used as a base for open-faced sandwiches known as smörgåsar. The bread's robust flavor makes it a versatile ingredient in Swedish cuisine, appreciated for its historical significance and unique taste.
