Birka Flatbread (Barley-Pea Flatbread)
Original
There is no manuscript recipe. The evidence is twofold:
Archaeological: Charred flatbread fragments recovered from Birka graves (8th–10th century Swedish trading center). Analysis by Ann-Marie Hansson showed barley and pea flour composition. Published in Hansson, "Pre- and Protohistoric Bread in Sweden," Civilisations Vol. 49 (2002).
Textual: The Rígsþula (Poetic Edda, 13th century) describes bread by social class — coarse barley bread for thralls, finer loaves for karls, white wheat bread for jarls.
Neither source gives a recipe with instructions. The evidence is compositional and social, not procedural.
My Redaction
Serra & Tunberg, An Early Meal: A Viking Age Cookbook & Culinary Odyssey (Chronocopia, 2013) contains a reconstructed barley-pea flatbread based on the Birka archaeological evidence. This is the standard published reconstruction.
Basic method (paraphrased from general knowledge of the reconstruction):
- Mix barley flour and pea flour (roughly 2:1 or equal parts)
- Add water to form a stiff dough
- Pat into flat rounds
- Cook on a hot stone or dry griddle/plancha
For hospitality service: Dense, unleavened flatbreads. Make them thin for best texture. Pairs well with Gravlax as a Scandinavian pairing on the spread.
