The Density Secret
When searching "a cup is how many grams", the answer depends on what you're measuring. Think of it like this: a cup of feathers vs a cup of rocks - same volume, different weight!
⚠️ Why This Matters:
- • Cookies spread thin? Too little flour (under-measured cups)
- • Cake too dense? Too much flour (over-packed cups)
- • Frosting too sweet? Wrong sugar conversion used
