Their 'sticks' or butter actually show you what tablespoon is.
I actually have cups, but they are metric so still don't work with US recipes.
And the number of times you see 'yellow cake mix'.
And then I watch masterchef (actually I watch the British Australian and US versions) and there are some fantastic cooks.
And masterchef junior - 8 year olds making beef wellington!
After all that I do think there are merits to weighing and using ratios (which is what cups are) depending on what you are cooking.
A basic sponge cake works best if you weigh the eggs and then add the same weight of butter, flour and sugar but it will still work out with 2 eggs, and 125g or 4oz of the dry ingredients.
And yes I know Australia uses metric cups some of the time, I brought a children's cook book for my niece with some Australian cup measures.
And I also admit to using condensed soup in my slow cooker.
