1. Overproofed — it fermented too long and lost the strength to rise in the oven. 2. Weak shaping — not enough surface tension during final shaping, so it spreads outward instead of up. 3. Starter wasn’t strong enough — using starter before or after peak can mean less oven spring. #sourdough #sourdoughbread #sourdoughforbeginners #sourdoughbaking #leaven
