Some of those old measurements may have been more accurate than thought. A wineglass with a specific volume was highly desirable to a Butler who was responsible for the Boss's drinkables. Thats been true for all the time since bottles were invented and manufactured. Miz Farmer was Correct. Cooking is a kind of chemistry, and precision leads to repeatability. I DO know this: one reason for lousy coffee across the country, particularly in gas stations and such, is the term "cup".Properly, a coffee cup is SIX oz., NOT eight. Yet when the counterhops fill a coffeemaker, they use the 8 oz measurement. This results in 20 percent less coffee in the mix, and thus, VERY WEAK COFFEE. This is consistent in road stops from Maine to Moana Loa. The only worse thing is using a dirty coffeepot to make Iced Tea....
