The Lady's Own Cookery Book, and New Dinner-Table Directory‪;‬

In measuring quantities, be extremely exact, having always some particular vessel set apart for each ingredient (best of earthenware, because such cannot retain any smell) wherewith to ascertain your quantities. Do nothing by guess, how practised soever you may deem yourself in the art: nor say "Oh! I want none of your measures for such a thing as a little seasoning," taking a pinch here and there. Be assured you will never in that way make a dish, or a sauce, twice in the same manner; it may be good by chance, but it will always be a chance, and the chances are very much against it; at all events it will not be precisely the same thing, and precision is the very essence of good cookery.
