I just realized while cooking that a measuring-cup cup (as measured out as 250mL in a glass measuring cup) is the same amount(s) as one of the actual plastic baking measuring cups that go inside each other like Russian dolls lol
I thought they were different somehow (something something imperial metric yadda yadda yaddda)
Your turn to come clean Lemmings!
**EDIT: to clarify, I mean volumetrically for measuring liquids
OP thought they were different as in different volumes, and then came to understand their mistake. you then came in to proclaim that they are different, then described how certain containers are harder to measure certain materials. Regardless of ease of use, a cup is a cup is a cup, so long is the “cup” in question is 8 oz of volume. Yes, some measurement tools have a different physical shape and may be more difficult to use for certain tasks, but that was not the “difference” being misidentified.
Also, you absolutely could use a glass measuring cup for flour, just tamp it down and go slowly, but that’d be stupid. Regardless, this is why using weight measurements for baking is vastly superior to using volume.
