Mix the water, starter, and 3 cups (360 g) of the flour in a large basin until well-combined.
Add another (180–240g) of flour once the salt, sugar, yeast, and gluten have been thoroughly combined. A slack (sticky) dough produces a light loaf; stir until the dough comes away from the bowl's sides, adding only enough extra flour as needed.
Knead the dough for 8 to 10 minutes by hand on a work surface that has been lightly oiled, or for approximately 7 minutes in a stand mixer. This dough may also be worked by running it through the dough cycle on your breadmaker; once it has done, transfer it to a bowl so it can rise as instructed below.
The dough should be placed in an oiled basin, covered, and allowed to rise for about 90 minutes or until it has doubled in size.
