Used a couple of US recipes recently and most of the ingredients are in cups, or spoons, not by weight. This is a nightmare to convert. Do Americans not own scales or something? What's the reason for measuring everything by volume?
I'm amused that my logic is the same but opposite of yours: why the fuck should I scoop and level something to get an "exact measurement", when I could just dump into a container on a scale and get an actual exact measurement.
So you don't have to modify the amount when the recipe called for kosher salt but you only have sea salt. A cup of pasta? Depending on the type you end up with vastly different weight
