For what its worth, a mug is one and one third cups, or 205ml or 7fl oz.
I agree that recipes should be as clear as possible.
I also agree that "cups", "teaspoons", "desertspoons" and "tablespoons" are pretty much universally established measures (as you've defined CP) for cooking. They also appear in most recipe books. After all, who's ever seen a recipe that says "add 5ml" of something rather than "add a teaspoon"? Although the former would be more precise and less ambiguous of course

I also agree that "ladles", "dollops", "bags", "chef's spoon", etc, are so poorly defined as to be almost meaningless (unless defined in the recipe itself of course).
You've got to admit though, it's a bit alarming when one person thinks a ladle of base sauce is about 40ml and another thinks its about 142ml!

But, I do have one question concerning your assessment of the volume of a mug CP

If 1 cup = 250ml (9
UK fl oz) and 1 mug = 1 1/3rd of a cup, surely one mug = 333ml (12
UK fl oz)?
Just trying to clarify......or maybe its just be being anal? :

Hmmm....maybe YF is correct, after all, then!
