STOCK

For home cooks, the biggest problem with stock is having it around when you need it. So make as much as you can manage  three gallons, say. To save space, you can reduce the stock so that it’s extra concentrated, and reconstitute it with water to taste when you’re ready. Refrigerate and skim the fat, if you like, then freeze in containers of varying sizes, or in ice cube trays.

STOCK-MAKING MATERIAL

Scraps of poultry (most of the chicken parts we don’t eat are good for stock), meat (again, especially the less-used, bonier parts) or fish (heads and skeletons in particular), vegetable trimmings, bones and more. Keep separate bags for each, adding to them when you can. Remember, though, that stock is not garbage soup: Carrot and potato peels, cabbage cores, and the like can be used, but in moderation. Animal organs are best avoided (fish gills and guts must be removed, and offal in general makes bitter stock).

BREAD, BREAD DOUGH, BREAD CRUMBS

Freeze dough in well-wrapped balls; defrost until it regains springiness. (It will never rise quite as high as unfrozen dough, but it works nearly perfectly for pizza or focaccia, and well enough for other uses.) Good crusty bread, wrapped in aluminum foil, can turn lighter dishes into meals  just defrost in the foil at 350 degrees or so for 10 minutes, then crisp up, unwrapped, at slightly higher temperatures. (I’m talking about crusty bread; sliced bread can be defrosted on the counter or in a toaster.) And stale bread can be made into crumbs in a blender or food processor, stored in a container, and added to at will.

PASTRY AND PASTRY DOUGH

Most cake and cookies freeze pretty well, carefully wrapped. Or make a frozen log of “refrigerator” cookies to slice and bake later. Same with biscuits: make a whole batch or double batch of biscuit batter, bake just enough for dinner, and freeze the rest.

TOMATOES AND TOMATO SAUCE

Tomato sauce is best frozen in zippered bags with the air squeezed out. If you have ripe tomatoes, core, quarter, and throw them in a bag; as they thaw the skins will slip off, a bonus. (The frozen chunks separate easily so you can just break off a couple for soups, stews, salsas, sauces and so on.) You can also freeze unused portions of canned tomatoes, preferably in their juice.

BACON

Or pancetta, prosciutto, smoked ham hocks, prosciutto bones, etc. Wrap tightly in plastic and cut off pieces as you need them. (Or cut before freezing  you might need a butcher to do this in the case of big bones.)

FRESH HERBS

If you have extra herbs, your four best options are: Make pesto by puréeing the herb with oil and whatever other seasonings you like; make “pesto,” a purée of herb and water, with or without other seasonings; make compound butter; chop herbs, and freeze in ice cube trays covered with water.
