So I put Hauke to a use and made a small batch of sourdough yesterday for testing. Following this Youtube Video, I made it “by feel” using a ratio of 3:2:1 (flour:water:sourdough). After letting it sit for one night it almost doubled in size and got really nice and fluffy (and a hell of a sticky substance). Baked it for 40 mins. in my trusty dutch oven and got this nice result.
