How to Fill Dry Measuring Cups
Here is how to measure dry ingredients accurately in a cup:
- Ensure the dry ingredient is loose and lump-free. Sieving or lightly whisking the ingredient is an easy way to get rid of lumps. This is perfect for flour or sugar (powdered sugar). Humid environments can cause lumps and clumps to form.
- Next, spoon the dry ingredient into the measuring cup. Fill it until it overflows.
- Place the cup onto a stable and level surface.
- Level the flour or dry ingredient off with the back of a knife or a straight utensil.
Do not pack the dry ingredient firmly into the cup. This can result in an inaccurate result.
