Give the flour a head start
Combine 250 g bread flour and 250 g warm water. Mix thoroughly, cover, and leave on the counter for 30–60 minutes.
This flour-and-water rest is an autolyse. It gives the flour time to absorb water and begin developing gluten, the stretchy network that holds gas in the dough. Only half the recipe’s flour is resting here; the remaining flour, salt, malt, and yeast go in during Sprint 2.
Checkpoint: No dry flour pockets. Expect a wet, sticky, doughy mess: this portion is at 100% hydration, with equal weights of flour and water. It will not hold a tidy ball. The finished dough reaches 70% hydration once Sprint 2 is incorporated.
