things people ask

• Why does my bread dough feel stiff when I measure bread flour by the cup?
  A scooped cup of bread flour can hit 145-160 g instead of the intended 120 g, and that extra 20-40 g lowers the dough's hydration percentage by several points. With bread flour's higher gluten potential, that shift is felt fast: the dough resists kneading, the crumb tightens, and the crust thickens. Spoon the flour into the cup, level with a straight edge, or weigh it for sandwich loaves and focaccia.
• Can I swap bread flour cup-for-cup with all-purpose in a recipe?
  By volume, yes — both sit around 120 g per cup at the spoon-and-level convention, so a one-to-one cup swap is reasonable for cookies, pancakes, or quick breads. The difference is protein, not weight: bread flour's 12-14% versus all-purpose's 10-12% means chewier cookies and a sturdier crumb. For yeast doughs you usually want bread flour; for tender cakes and biscuits, stick with all-purpose.
• How many cups of bread flour are in a 5-pound bag?
  A 5-pound bag is roughly 2,268 g, which works out to about 18.9 cups at 120 g per cup. In practice you'll get 18 to 19 cups depending on how settled the flour is and how carefully you spoon-and-level. A standard boule recipe using 500 g of bread flour pulls just over four cups, so a 5-pound bag covers about four to five loaves.
