things people ask

• How many grams are in one cup of coconut flour?
  Spoon-and-leveled, one US cup of coconut flour is around 128 g, matching the King Arthur weight chart. Because the flour is so dry and fluffy, scooping straight from the bag can pack in 10-20 g extra, which then drinks up even more liquid in the batter. If a recipe gives only a cup figure, weighing to 128 g per cup keeps the egg-to-flour ratio predictable.
• Can I swap one cup of coconut flour for one cup of all-purpose flour?
  No - coconut flour absorbs roughly four times more liquid than wheat flour, so a 1:1 swap will give you a dry, crumbly brick. The usual conversion is about 1/4 cup coconut flour (32 g) per 1 cup of all-purpose flour, plus an extra egg or two and additional milk or water. Recipes built around coconut flour from the start are a safer bet than retrofitting a wheat recipe.
• Why does my cup of coconut flour weigh different amounts each time?
  Coconut flour clumps as it sits and absorbs ambient humidity, so a freshly opened bag scoops lighter than one that has been on the shelf for a month. Sifting before measuring breaks up the clumps and gets you closer to 128 g per cup. If your kitchen is humid, store the flour sealed with a desiccant packet and weigh rather than scoop for cake and muffin ratios that need precision.
