Things get a bit weird now! Apparently these people did not take much notice of their pals the Egyptians.
Instead of using yeast (obviously not enough sunshine around!) these people mixed pot ash from their fires and sour milk into their dough to make it rise. Nice!!
But all is not lost!! Around this time some clever person found a way to improve the flour by using handsized mill stones. But they still did not use ovens, preferring instead to use "griddles".
