Corn Flour
Corn flour weighs 126g per cup and is finely ground from whole corn kernels — different from cornstarch, which is only the starchy part. In British English, corn flour often means cornstarch, so check your recipe's origin. It adds a mild corn flavor and yellow color to baked goods, tortillas, and breading. Corn flour produces a softer crumb than cornmeal. Store in an airtight container in a cool place for up to a year.

03 // WHY IT MATTERS
If your cookies spread, your bread is gummy, or your cake sinks — flour weight is usually why.
A scooped cup of flour can weigh anywhere from 125g to 180g. That's a 44% range — enough to wreck a cake.
Modern recipes use the spoon-and-level method: fluff the flour, spoon it into a dry measuring cup without packing, then sweep flat with a knife.
The scoop method — pushing the cup directly into the bag — packs in 40-50% more flour.
