Take flour made from wild wheat and barley, mix with the pulverised springs of flowers, add liquid, then bake.
According to scientists, this is the recipe for the world’s oldest bread, dating back more than 14,000 years.
The bake would have looked like a flatbread and savoured a little bit like today’s multi-grain dough, they say.
Our ancestors may have exploited the bread as a cover for roasted flesh. Thus, as well as being the oldest dough, it may also have been the oldest sandwich.
“This is the earliest evidence we have for what we could really call a cuisine, in that it’s a mixed food product, ” Prof Dorian Fuller of University College London told BBC News.
