Mock Turtle Soup, Thickened

It needs one gallon of soup for twelve persons. Proceed exactly the same as for the clear mock turtle only leaving out the fecula thickening. Put four ounces of butter into a saucepan on a slow fire, and when melted, mix in with it a quarter of a pound of flour, cook it slowly to obtain a blond roux, which then moisten with clear turtle stock, until it becomes the consistency of a light sauce, cook it slowly and keep despumating it for half an hour, then strain it through a sieve or tammy, and return it to the fire in a very clean saucepan, and after bringing the liquid up to a boil, despumate it again. Add the quenelles, the calf's head cut in pieces, and the pulp of a lemon without any peel or pips, also half a gill of sherry wine for each quart of soup.
