@idbrii @pierstoval @grumpyoldtechie @jxrxme There is that. A cup of sugar is reasonably well defined, but flour? - how hard do you pack it down?
And I've never understood how you're supposed to measure a cup of butter. I guess if you've got a whole churn full in your dairy you can scoop it out, but if all you 've got is those blocks from the supermarket?
