How to measure cornstarch
- Stir the flour in its bag to loosen it.
- Spoon it into the cup until it mounds, without tapping or shaking.
- Level it with the back of a knife. Scooping straight from the bag packs in more.
- For the same result every time, weigh it: put the bowl on the scale, press tare, then add cornstarch to the weight above.
