Food and Flavor: A Gastronomic Guide to Health and Good Living
“ Cows and pigs, to be sure, eagerly eat apples, and other fruits, and so do horses; they eat them though they be sour; but if you give them a whole bushel, they pick out the sweet ones first.The liking for sour things is a human attribute. [561] School children are often more eager for a pickle than for a stick of candy; and adults as well as the young ones enjoy tart or sub-acid fruits of all kinds. What could be better than a pie or a tart made of green gooseberries or sour currants? I would give all the confectionery and sweet cakes in the world for a tree of sour cherries. ”
