Cut very evenly, from a firm stale loaf, slices nearly an inch and a half thick, and with a plain or fluted paste-cutter of between two and three inches wide press out the number of patties required, loosening them gently from the tin, to prevent their breaking; then, with a plain cutter, scarcely more than half the size, mark out the space which is afterwards to be hollowed from it. Melt some clarified beef-marrow in a small saucepan or frying-pan, and, when it begins to boil, put in the patties, and fry them gently until they are equally coloured of a pale golden brown. In lifting them from the pan, let the marrow (or butter) drain well from them; take out the rounds which have been marked on the tops, and scoop out part of the inside crumb, but leave them thick enough to contain securely the gravy of the preparation put into them. Fill them with any good patty-meat, and serve them very hot on a napkin.
Obs.— These croustades are equally good if dipped into clarified batter or marrow, and baked in a tolerably quick oven. It is well, in either case, to place them on a warm sheet of double white blotting-paper while they are being filled, as it will absorb the superfluous fat. A rich mince, with a thick, well-adhering sauce, either of mutton and mushrooms, or oysters, or with fine herbs and an eschalot or two; or of venison, or hare, or partridges, may be appropriately used for them.
