When it comes to weighing flour, there is no guarantee in accuracy unless you measure it properly. Once flour has been packed it becomes heavier. It is important to fluff your flour and measure it in a measuring cup correctly. There is no need to place the flour on the scale if you refer to the amount-to-weight formula. You do not have to be an expert baker to weigh your flour without the use of a scale. All it takes are a few kitchen essentials.
Fluff the flour inside of a bag or container of all-purpose flour by stirring it with a fork or whisk. Do this motion until the flour is light and unpacked.
Spoon all-purpose flour into a measuring cup (one-cup size) with a regular dinner spoon. Loosely fill until the flour heaps just past the top of the measuring cup. Do not pack the flour or tap the cup to level it.
Level the measuring cup off by using a straight edge across the top of the cup. Do so in one steady movement. The flat edge of a butter knife works well.
Dump the measured flour into your desired container. This one cup amount is the equivalent of 125 grams. No scale is needed to determine this weight.
Continue steps as needed until you have reached your desired amount of flour you wish to weigh. Simply multiply the ounces/grams by the number of cups you use.
If you measure the flour in any way other than the one described, the weight will not be accurate.
