Use warm (not hot) water: about 75–80°F (24–27°C) encourages activity without stressing the starter. Keep your hands wet when handling the sticky dough to prevent tearing and sticking. Score confidently: make a quick, decisive slash to help the loaf open where you want it to bloom. Let the loaf cool fully (at least 1 hour) before cutting to set the crumb and avoid gummy texture.
