So do the carrot peels, the papery outer layer of the garlic, the leafy tops of the celery that never fit in the crisper drawer, and the stems from a bunch of parsley you bought for a single tablespoon. None of it goes into the trash, and none of it goes into a pot yet. It goes into a bag in the freezer, where it waits, quietly accumulating, until one cold afternoon the bag is full and you make stock from things you had already paid for and were about to throw away. ## What gets thrown away Most kitchens lose food in two places. One is the forgotten container at the back of the refrigerator, the leftover that turns while nobody is looking. The other is the cutting board. Every time you trim a vegetable, a fair share of it goes straight to the bin: the root ends, the tough outer leaves, the skins, the tops. It does not feel like waste, because it does not feel like food. It feels like the part you take off before the cooking starts. The federal government's own estimate is that somewhere between thirty and forty percent of the food supply in this country is never eaten. A great deal of that loss happens long before anything reaches a home, on farms and in warehouses and stores, and no freezer bag will fix it. But the part that happens in your kitchen is the part you can actually change, and the cutting board is the easiest place to begin. Those trimmings are not tasteless. The skin of an onion carries color. The tops of celery and leek carry much of the plant's aroma. Mushroom stems are dense with the savory depth that makes a broth taste like something. Thrown out, they are garbage. Simmered, they are the base of a week of soups. ## How the bag works The method is almost too simple to call one. Keep a large freezer bag or a lidded container in the freezer. Every time you cook, the clean trimmings go in instead of into the bin. When it is full, you make stock. A few habits make it work well: **Wash before you peel.** If the scraps are going to become broth, they need to be clean when they come off the vegetable. Scrub the carrot, then peel it. **Keep the good scraps, skip the troublemakers.** Onion, leek, shallot and garlic trimmings, carrot peels and ends, celery leaves and bases, fennel fronds, parsley and thyme stems, mushroom stems, the ends of zucchini, tomato cores and corn cobs all belong. The cabbage family does not: broccoli stems, cauliflower cores, cabbage, kale and Brussels sprouts turn a stock sulfurous and bitter as they simmer. Beet peels will dye everything red. Potato peels make the liquid cloudy and starchy. Leave those out, or use them somewhere else. **The freezer is not a compost bin.** Anything slimy, moldy or already past its best does not improve with freezing or simmering. The bag is for trimmings from food you were about to cook, not for food that went bad. **Bones go in their own bag, if you use them.** The carcass of a roast chicken, the bones from a pork shoulder, a few leftover wings: all of these make a richer stock than vegetables alone. Keep them separate so you can decide each time whether you want a vegetable broth or a meat one. **Add a rind.** The hard end of a wedge of Parmesan, the part you cannot grate, gives a pot of broth a round, savory depth out of all proportion to its size. Keep those in the bag too. ## Making the stock When the bag is full, empty it into your largest pot, frozen. There is no need to thaw anything. Add a bay leaf and a few peppercorns if you have them. Cover with cold water by an inch or two and bring it slowly to a bare simmer, the kind where a bubble breaks the surface every second or so. Then leave it alone. A vegetable stock has given up most of what it has in about an hour; much longer and it can start to taste flat or faintly bitter. A stock with bones wants more time, three or four hours at that same lazy simmer, which is what draws out the body that makes a good broth set into a soft jelly when it is cold. Keep it below a boil. A hard boil churns the fat into the liquid and leaves it cloudy and greasy. Do not salt it. A stock is an ingredient, not a finished dish, and you cannot take salt back out. Season whatever you make with it instead, once you know what that is. Strain it through a fine sieve, pressing gently on the solids, and then the spent scraps really are done. If you keep a compost pile, this is the moment they go to it, having given everything they had twice over. ## Keeping it safe The one part of this that deserves care is the cooling. A large pot of hot liquid holds its heat for a long time, and the standard food safety guidance is to get cooked food into the refrigerator within two hours. Divide the stock into smaller, shallow containers so it cools faster, rather than putting the whole pot in the refrigerator to warm everything around it. Refrigerated, stock keeps for three or four days. Frozen, it keeps for months, though it is at its best within the first two or three. Freeze some flat in bags so they stack like files and thaw quickly. Freeze some in an ice cube tray, then pop the cubes into a bag, and you will always have a few tablespoons for a pan sauce or a pot of rice. ## What changes The practical return is real. A quart of stock from the store is not cheap, and a full bag makes several. Rice cooked in broth, beans simmered in it, a pan sauce finished with a splash of it: each one tastes noticeably better than the version made with water. But the larger change is in how you stand at the cutting board. Once the bag is in the freezer, the onion skin is no longer trash. You start to see the whole vegetable as food, including the parts you used to trim away without thinking. You buy the leeks with their long green tops. You keep the parsley stems. A small, steady attention settles over the kitchen, the kind that notices what is there before reaching for what is not. That attention spreads. People who keep a scrap bag tend to notice the half onion in the refrigerator door, the wilting celery, the heel of bread. The bag teaches the habit without asking for any virtue at all. It only asks you to open the freezer instead of the trash can. ## Start this week Find a bag. Label it with the month so you know how long it has been gathering. Put it in the freezer tonight, and the next time you cook, let the trimmings go in instead of out. It will take a week or two to fill. When it does, choose a cold afternoon when you will be home anyway, put the pot on the back burner and let the house fill with the smell of it. It is the smell of a kitchen that has stopped throwing things away, and it costs nothing you had not already bought. --- Published by Creations Magazine.
