How to Measure All-Purpose Flour Correctly (Scoop vs. Scale)
Aerate the flour with a whisk or fork first. Spoon gently into the measuring cup until mounded above the rim, then sweep a flat metal spatula across the top. Never pack or tap the cup.
Excess flour absorbs precious recipe liquids and over-develops gluten, leading to dry, dense cakes, crumbly cookies, and sunken domed tops.
1-to-1 Substitute for All-Purpose Flour: Cake Flour or 1:1 Gluten-Free Blend
For 120g AP flour, use 113g cake flour + 15g cornstarch, or 120g 1:1 GF blend with xanthan gum.
Yields a softer, more delicate crumb structure with reduced chew.
Storage, Shelf-Life & Humidity Impact on All-Purpose Flour
Pantry Storage & Shelf-Life
Store in an airtight container in a cool, dark, dry pantry away from sunlight and spices.
Estimated Shelf-Life: 8 to 12 months at room temperature; up to 2 years frozen.
Kitchen Humidity & Density Impact:
Flour is hygroscopic: in humid kitchens (>70% RH), it absorbs ambient water vapor, increasing density by 4–6% without expanding in volume.
