Let's make "Supper Bread"! Civilization sustaining bread.

For 7.5 thousand years humans existed primarily on bread...THIS BREAD. I have perfected a simple method of making THE bread that sustained civilization for a very long time. 3 ingredients, whole grain, sourdough, real bread. NEVER MEASURING, NEVER DISCARDING AND NEVER REFRIGDERATING. When life was more about survival rather than managing excess, this is how bread was made.
