How bread flour compares with other flours & starches
127 g per cup places bread flour in the middle of its category — lighter than vital wheat gluten (145 g) and heavier than self-rising flour (125 g).
That gap matters when you substitute by volume: use a cup of vital wheat gluten where the recipe wanted bread flour and you have added about 18 g extra — 14% more than intended. Weighing instead of scooping removes the problem.

- Why do my numbers differ slightly?
- Flour compresses. Dipping the cup into the bag can pack in 20% more than spooning it in loosely and levelling the top, and sifting first makes it lighter still. A scale removes the guesswork.
