There was a group of Christian farmers in Russia during the 1870's. Facing extermination or exile, they had their children pick through the wheat, saving the best kernels in giant seedbags. The rest they baked into hard rolls to sustain them on their journey to America.
Once here, they settled in the unforgiving prairie land of the Midwest. But their healthy, hardy winter wheat thrived in the harsh conditions. Eventually it became the standard throughout America's farmland, the breadbasket of the world.
