Wet the bread before it goes back in

Because stale is not the same as dry, the people here say. One account gives the mechanism the others use without naming it: the starch in bread sets into crystals as it sits, and heat with a little water lets the starch take the moisture back and go soft again; four separate conversations do it in the microwave, with a spray, with a mug of water standing beside the bread, or with a damp paper towel around the slice, and one runs the bread under the tap and wraps it in foil for the oven. A few of the accounts argued about whether that counts as “reheating” or physics or chemistry, five accounts finding the framing pedantic; the action is the same. The timing is the honest gap: three accounts say eight seconds will not work for everyone because wattage and the amount of bread change it, one says a ceramic mug soaks up heat so give it ten seconds instead, and three say the result is a texture some find unpleasant — chewy, though one of them prefers the microwave for pizza. For crisps the water is not needed; one account says the burst drives moisture out, the way the fryer did, and the crunch returns on cooling. Whether it works on crackers is asked and not answered — a gap in these conversations; it worked on a corn tortilla chip for one account; rice, one account rates eight out of ten and one caution says do not. One exchange asks whether the tip is only for people who cannot afford new chips, and the answer given is no — the bag you have is the bag that is stale, and the shop is further away than the microwave.

The bag, the seasoning, the recycled towel and the twist tie — the safety line above has them. The rest of the cautions are about results rather than fire: do not repeat the microwave on the same chips, two cautions say, because the second time they go hard; popcorn goes chewy and wants the oven, one contraindication and one caution agree, two accounts to two in one conversation on whether the microwave suits every snack; and microwaved bread has to be eaten at once. One account notes the energy cost as a downside. The argument about whether the oven does the whole job better is rendered below, three accounts to three.

Then it is an ingredient, and this is where the people here agree most. Six separate conversations cube or blitz stale bread and dry it in a low oven for croutons, breadcrumbs or a breading; one account makes croutons first and blitzes them later only if crumbs are needed, one saves heels in the freezer until there are enough to process, and one lets them air-dry for a few days instead, two accounts to one on freezing first. Five conversations say stale bread is the right bread for French toast or bread pudding, because dry bread drinks the custard; three say stale tortilla chips want frying up with salsa into chilaquiles rather than reviving; single accounts add stuffing, panzanella, meatballs and patties, dumplings, and muffins blended with ripe bananas and eggs. Two cautions on storing crumbs: dry them fully and cool them before jarring, or they mould, and check the jar now and then for weevils. Whether any of this is worth the bother is argued three ways in one conversation — three accounts to three that the savings are pennies against the storage and the memory it takes, three to three that eating the heels as they are beats processing them, and two to three that shop crumbs are fine; the accounts’ own decider is how much bread your household would otherwise throw away and how much you mind a small kitchen chore. One objection says commercial crusts taste of additives; the answer given is to buy better bread.

Scrape it with a knife, the people here say — seven accounts to three in one conversation choose the knife over the cheese grater one account proposed, because the knife is already in your hand and washes in a second; one account rubs the two burnt faces together instead, and one says shaving off the burnt layer is standard in restaurant kitchens. Two accounts say the burnt taste and smell stay however you scrape, two say the scraped bagel is fine, and one says it depends whether the burn is on the surface or has gone into the crumb; a high-rated caution, two accounts, says the jokes about power tools are jokes — nothing with a motor near food. The line the accounts do not have is the UK Food Standards Agency’s: acrylamide is a chemical that forms when starchy foods such as bread and potatoes are cooked above 120°C, and its advice is to aim for a golden yellow colour or lighter when toasting, baking, frying or roasting. That is a reason to scrape the black off, and a better reason to toast lighter next time, which one account says is the real tip.

The freezer, two separate conversations say twice over — freeze the loaf when you buy it or slice it, and take slices out as you need them; that has its own page, linked below, with the fridge-makes-it-worse finding. One account keeps opened crisps in a large glass jar with a tight lid and reports months. The bread-bag argument is one account each way: one says a cotton pillowcase slows staling by letting humidity move, and one correction from another account says their homemade loaf went stale faster in a cotton bag than in a plastic one; the accounts’ own decider is whether the bread is homemade or commercial and how damp your kitchen is, and this page does not settle it. One account notes that reviving frozen bread is a different job from reviving stale bread — longer, and better under a grill. How long a revived crunch lasts, which oven temperature counts as low, and whether sourdough behaves like sliced white are gaps in these conversations, and this page leaves them open.
