things people ask

• Why do my cup measurements vary?
  Flour density depends on how it's measured. Spooning into the cup yields ~120 g; dipping the cup straight into the bag packs the flour and yields ~145 g. Using the same method every time matters more than which method.
• Should I weigh or measure flour for baking?
  Weighing in grams is more reliable, especially for yeast doughs and pastries where hydration matters. A digital kitchen scale removes the spoon-vs-scoop variance entirely.
• Is sifted flour the same weight per cup?
  No. Sifted flour aerates and weighs less per cup — typically 110–115 g instead of 120 g. If a recipe says 'sift, then measure,' weigh after sifting to be safe.
