Having well buttered the inside of a nicely tinned stew-pot, cut ham into slices, and lay them at the bottom, with the beef, and veal, cut from the bones, which you must afterward break to pieces, and lay on the meat. Cover the pan closely, and set it over a quick fire. When the meat begins to stick to the pan, turn it; and when there is a nice brown glaze at the bottom, cover the meat with cold water. Watch it well, and when it is just coming to a boil, put in half a pint of cold water. This will cause the scum to rise. Skim it well, and then pour in another half pint of cold water; skim it again; pour in cold water as before, half a pint at a time, and repeat this till no more scum rises. In skimming, carefully avoid stirring the soup, as that will injure its clearness.
In the mean time prepare your vegetables. Peel off the outer skin of the onions and slice them. Pare the turnips, and slice them also. Wash clean and cut into small pieces the carrots, and the celery. If you cannot obtain fresh celery, substitute a large table-spoonful of celery seed, tied up in a bit of clear muslin. Put the vegetables into the soup, and then place the pot on one side of the fire, where the heat is not so great as in the middle. Let it boil gently for four hours. Then strain the soup through a fine towel or linen bag into a large stone pan, but do not squeeze the bag, or the soup will be cloudy, and look dull instead of clear. In pouring it into the straining cloth, be careful not to disturb the ingredients at the bottom of the soup-pot.
This soup should be of a fine clear amber colour. If not perfectly bright after straining, you may clarify it in this manner. Put it into the stew-pan. Break the whites of two eggs into a basin, carefully avoiding the smallest particle of the yolk. Beat the white of egg to a stiff froth, and then mix it gradually with the soup. Set it over the fire, and stir it till it boils briskly. Then take it off, and set it beside the fire to settle for ten minutes. Strain it then through a clean napkin, and it will be fit for use. But it is better to have the soup clear by making it carefully, than to depend on clarifying it afterward, as the white of egg weakens the taste.
In making this (which is quite a show-soup) it is customary to reverse the general rule, and pour in cold water.
