Yes, that is what I meant, though put badly. In other words my idea was that the volume in those measurements called spoons, etc are exactly the same in the UK and in the US. So if a formula calls for ingredients measured in spoons and cups, the ratio is changed when the volume of the cups changes. So typicly if the origin of the formula is the US, with smaller cups, then the flavoring measured in spoons becomes blander if UK cups are used because the ratio of spices to say flour is decreased.
Of course this is not the real problem. After Jean Redpath had done the folk circuit in America, her mother banned her from the kitchen in Fife because she actually produced food with flavo[u]r. In my college at St Andrews, the cook used to have to sneak out into the garden after dark to pick bay leaves to add to the pasta sauce.
