Why I do this
I'm Hendrik, a software engineer turned sourdough obsessive. I spent years figuring out why my bread failed, and discovered that most recipes don't explain the why.
So I built The Sourdough Framework: a free, science-based guide that teaches principles, not just steps. Because once you understand fermentation, you can bake great bread anywhere, with any flour, in any oven.
My mission: enable everyone to bake incredible bread at home. No expensive tools required.
