Why bread goes stale: starch retrogradation, not drying

A 5-beat faceless video outline for “Why bread goes stale: starch retrogradation, not drying” in the Cooking science (no faces) niche, derived from caption timing of 2 reference videos.

Angles

• Cold-open on the contradiction: stale bread hardens while a stale cookie softens — so "drying out" cannot be the whole story
• Split staling into two processes: water migrating from crumb to crust, and starch retrogradation (starch re-crystallizing and squeezing water out)
• Make the fridge the surprise: cold speeds retrogradation, so refrigerated bread firms faster even in a sealed bag
• Close on the reversible fix — a few minutes in a warm oven softens it temporarily — and freezing for longer storage

Beat-by-beat structure

1. Hook (0:00–0:30): a hard slice of bread next to a soft stale cookie.
2. Process 1 (0:30–1:30): moisture moves from wet crumb to drier crust (and from air into dry cookies).
3. Process 2 (1:30–3:00): retrogradation diagram — starch crystals form, water is pushed out but stays in the loaf.
4. Temperature (3:00–4:00): fridge vs counter vs freezer pace.
5. Rescue card (4:00–5:00): warm oven reheat = temporary; store sealed at room temp or freeze. Original narration only.
