When the oysters are small, from two to three dozens for each pint of soup should be prepared, but this number can, of course, be diminished or increased at pleasure. Let the fish (which should be finely conditioned natives) be opened carefully; pour the liquor from them, and strain it; rinse them in it well, and beard them; strain the liquor a second time through a lawn-sieve or folded muslin, and pour it again over the oysters. Take a portion from two quarts of the palest veal stock, and simmer the beards in it from twenty to thirty minutes. Heat the soup, flavour it well with mace and cayenne, and strain the stock from the oyster-beards into it. Plump the fish in their own liquor; but do not let them boil; pour the liquor to the soup, and add to it a pint of boiling cream; put the oysters into the tureen, dish the soup, and send it to table quickly. Should any thickening be required, stir briskly to the stock an ounce and a half of arrow-root, ground very smooth in a mortar, and carefully mixed with a little milk or cream; or, in lieu of this, when a rich soup is liked, thicken it with four ounces of fresh butter well blended with three of flour.
Oysters, 8 to 12 dozens; pale veal stock, 2 quarts; cream, 1 pint; thickening, 1 1/2 oz. arrow-root, or butter, 4 ozs., flour, 3 ozs.
