"So it does, and it is, too. Now we come at last to my hobby; such an interesting hobby, too, Dolly; it is Scraps, or, Left-overs, if you like that better. And here you must study hard, for to my thinking you stand or fall as a housekeeper by your knowledge or ignorance of the subject.
"Of course you know the saying that a French family could live on what an American family throws away. There is something in the saying, though I will not admit it to be entirely true; but it is a fact that a good cook seldom has anything to put in her garbage pail, and it really is horrifying to see what people, especially poor people, do throw out: half-loaves of bread, good-sized bits of vegetables, bones that would have made soup, and lots of other things.
"To begin with bread, save all the odds and ends of that. Make crusts and hard ends into crumbs and sift them well; the half-slices make into bits of toast and use them at once, whenever you find them in the box, before they get very dry. No bit of bread should ever be wasted.
"Then there is fat of all sorts; the grease on top of soups, drippings from meat, bacon fat, everything of that sort is to be saved. Put the strips of fat through the meat-chopper and then put all in a dish with water, cover tightly, and set in the oven and let it cook till the water is gone. Strain it through cheesecloth, put it in a covered pail, and you will always have enough for frying without buying lard. When you use part of it and it gets brown, do not pour it back on the white fat, but put it by itself, and when you have enough cook it up again with boiling water, strain it twice, and it will turn white and as good as before.
"As to bits of meat, I have told you about those; use them up in soufflé or in hash, or any way you can. Some people insist that there are some things that one cannot properly use, such as an end of steak, but I have yet to find the bit of meat that is not good for something. The steak ends I pour boiling water over and scrape till the charred part disappears, and they make either hash of some sort or soufflé. If you cannot do any better, at least put the bits of meat into soup stock, and of course all the bones you have go with it.
"As to bits of fish, those go into patties or croustades; the patties are really baking-powder biscuits. I just cut out the middle, without opening them, and there is a perfect shell. I put a little butter inside, heat it well, and fill it with creamed fish or anything else. The croustades are one of the most useful things of all for serving left-overs. To make those you take slices of bread three inches thick and cut them into rounds with a biscuit-cutter; on top you mark a smaller circle. Dip each one in milk; drop it into hot fat and let it turn golden brown; fill it with creamed chicken or meat or fish or peas. A platter of croustades is a really attractive dish and as good to eat as it is to look at. If ever I have a round loaf of bread that I can spare I make that into a large croustade, too, especially for company. I cut out the middle till it is a good-sized shell, butter the inside, and brown it in the oven, and then fill it with creamed salmon, or anything else. Creamed oysters are delicious in it. That does not properly come under left-overs, but as it belongs with croustades I put it there, anyway.
"As to eggs, begin by saving all their shells and washing them; they do for clearing coffee. Of course you must not break a fresh egg for that. Then when you make mayonnaise out of the yolk of one, always make up a dish calling for one white, perhaps a little cake; or, whip it, sweeten with powdered sugar, mix with currant jelly, make it very cold, and serve it in two small glasses as currant fluff. It does for dessert after a heavy dinner. If you use the egg white first, do not let the yolk dry out, but stir it with a little cold water and you can keep it over a day or so till you need it; or make it up at once into mayonnaise, and do not put water in it.
"Vegetables, as you know, I have already told you a good deal about. Peel the potatoes carefully. When you have only a little bit of carrot or turnip, mix this with cooked peas; or put all three together and cream them. Put a slice of beet in corned beef hash; a spoonful of peas goes into an omelette; a carrot can be diced and added to beef stew; celery tops go into soup; mixed vegetables are to be made up into vegetable croquettes; cooked potato makes potato soup, and so on. Never let so much as a single pea escape your watchful care. Even in slicing an onion, remember not to cut through the middle, but to begin at one end, to keep it fresh for next time, and so on till it gradually disappears.
"Now, the worst of economies is yet to come, for to my mind utilizing bits of cold puddings and such things is most difficult. If you feel you must not eat up such left-overs at luncheon, and of course you ought to feel so, and yet there is not really enough to make a second dessert as it is, you have to face a problem at once. But here are a few things I have learned.
"Suppose you have a very little rice pudding left; mix some jam with it, beat in it the yolk of one egg, pour it into two little moulds, and bake them in a pan of water. They will come out nice little shapes of fruity rice, quite different from the previous pudding. Corn-starch left-overs can be thickened by reheating and adding more corn-starch; when it is all smooth, pour this into a baking-powder can to harden, then turn it out, slice it, dip each piece in crumbs, egg, and crumbs again, and fry in deep fat; they grow soft in the middle and are very good indeed; the French call them fried cream. Treat bread pudding in the same way, and serve with a nice sauce. When you make gingerbread, put some raisins and spice into part and bake separately. When you want this half, steam it up and serve as a fruit pudding with a hot sauce. You can crumb up plain gingerbread that is stale, add a little molasses to keep it together, and raisins and spice, and steam it that way, too. It is surprisingly like a plum pudding.
