broiled steak is more appetizing and delicate in flavor than some of
the cheaper cuts, but in proportion to the cost is not equal in
nutritive value; careful cooking and judicious flavoring render the
cheaper pieces of beef equally palatable. That expensive food is not

traditional diet of the Scotch people with their oatmeal and herring;
the Irish, potatoes and buttermilk; New England, codfish and potatoes,
and pork and beans; the Chinese, rice, etc. Monotony of diet, however,
