Cake flour is essential for creating delicate pastries due to its low protein content, which ensures a tender, light crumb. While it is a stable dry ingredient, its quality depends heavily on environmental conditions. Proper storage in an airtight container within a cool, dry pantry helps maintain the fine texture required for successful baking. However, exposure to humidity can lead to clumping or moisture absorption, while extreme neglect may allow pests or mold to develop over time. By monitoring your flour's texture and scent, you can ensure it remains a reliable staple in your kitchen. Understanding these shelf-life nuances helps prevent ruined recipes and ensures consistent results for every batch of cakes or pastries you bake.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
