"Also in response to @deb1973 - Even when dealing in cups not every one knows a cup is 8 oz. the Australian, and Canadian cups are 250 ml. the English cup measure is 285ml. it is only the US cup measure that is 8oz ( or 236ml.) and even US FDA has rounded up to 240ml. - I may be wrong but I believe Alton Brown is English so has become sensitized to the variability of "common sense" measures. I will also say that my pinch of salt is probably not the same as yours.
