Cups are good if the entire recipe is in cups because then you just pick any container you like and you don't need to weigh anything. You could use a wheelie bin and the ratios would still be right (you might have to adjust cooking time)
If it says "1 cup of flour, 1 egg" you're fucked though. A wheelie bin of flour with one egg in it, no one's gonna eat that.
