Sulpice Barué, Domestic French Cookery, 4th ed
“ When no more fat rises to the top, put in what quantity you please of carrots, turnips, leeks, celery, and parsley, all cut into small pieces; add, if you choose, a laurel-leaf, or two or three peach-leaves, a few cloves, and a large burnt onion, to heighten the color of the soup. Grate a large red carrot, and strew it over the top. Then continue to let it boil, gently but steadily, till dinner time. Next to the quantity and quality of the meat, nothing is more necessary to the excellence of soup than to keep the fire moderate, and to see that it is boiling all the time, but not too fast. ”
