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
No worries, old cookbooks are a bit of a wild ride so there could well be cups and all sorts of madness being used!
If you’re into that, the above channel is great; he has an old recipies series and goes into the history and compares and contrasts many sources and is really into the history. Cheers!
