How to measure pastry flour accurately
For the most reliable baking results, weigh pastry flour on a kitchen scale rather than scooping by volume. One US cup of pastry flour weighs about 120 grams (4.23 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts pastry flour and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: No pastry flour on hand? Blend two parts all-purpose with one part cake flour to land in the same protein range.
