Erin suggested I should put that on a t-shirt, after I explained the sourdough making progress to her.
Basically I create this culture of microorganism, feed them and adjust their environment according to their needs, so they reproduce a lot and evolve from generation to generation exactly how I want. Once their culture has grown strong, I take most of them away, bake and eat them. Then I go back to encourage the survivor to procreate, so the cycle can continue. Muahahahahaha!
Are you still wondering, why I like making bread?
