Why this matters
Before fixing anything, name the actual problem: too much water, too much heat, insufficient structure, poor storage, or an ingredient that cannot perform the original job. Then make the smallest useful correction. A careful repair preserves more food and teaches you something; random additions often create a second problem while hiding the first.
How to do it
Dry sound, mold-free bread in a low oven until crisp, cool it, then pulse or crush into crumbs. Store airtight and label the date.
What to look, hear, or feel for
The bread should smell clean and toasted, with no soft pockets before storage. Coarse crumbs suit toppings; fine crumbs bind meatballs.
When something goes wrong
Discard any moldy bread entirely because growth can extend beyond the visible spot. Toasting does not make moldy bread safe.
Try it in a real meal
These techniques help with everyday sauces, leftovers, substitutions, and produce that needs a sensible plan.
