Ralph Waldo Emerson said "A foolish consistency is the hobgoblin of little minds."
How right he was. My favorite breads to bake are sourdough breads and probably they always will be, but they take time, lots of time. What if you're struck with the desire to bake some bread and all you do is sourdough, then you're stymied unless you planned a day in advance. Recently I've overcome my sourdough fixation, and when no one is looking (just joking) I'll sneak a teaspoon of dehydrated yeast into my bread mix, and...well you know what that does. Or, I'll make some tortillas (yes, they're bread) with just flour and water. There's always a way. Rigidity is a dead end.
