How much cheese is a handful? How much more or less is a cupful? What is the capacity of a glass, a tumbler, or a soup ladle? What is the difference between a suspicion and a pinch? How much more is a good pinch? How much wine is a little, how many olives a few? When a book says a tin of chopped almonds or pomegranate juice what are you supposed to understand by that?–Elizabeth David (1913-1992), English food writer
