Mrs. Beeton, The Book of Household Management
“ Beetroot contains twenty parts sugar. Everybody knows that the beet has competed with the sugar-cane, and a great part of the French sugar is manufactured from beet. Beetroot has a refreshing, composing, and slightly purgative quality. The young leaves, when cooked, are a substitute for spinach; they are also useful for mixing with sorrel, to lessen its acidity. The large ribs of the leaves are serviceable in various culinary preparations; the root also may be prepared in several ways, but its most general use is in salad. ”
