Emulsion clinic: mayo / vinaigrette failures and the fix rule

A 5-beat faceless video outline for “Emulsion clinic: mayo / vinaigrette failures and the fix rule” in the Cooking science (no faces) niche, derived from caption timing of 1 reference videos.

Angles

• Cold-open on the kitchen contradiction: oil and water split in seconds, yet mayo stays smooth for hours — the reference opens exactly on that observation
• Name the emulsifier job (lecithin in yolk, mustard) before any recipe — droplets need a coat to stop merging
• Treat failures as diagnosable: oil added too fast, ingredients too cold or too warm — each with a visible symptom
• Close on label literacy: the same emulsifiers and gums hold store dressings together

Beat-by-beat structure

1. Hook (0:00–0:30): a jar of vinaigrette separating next to a bowl of mayo that holds — promise the rule behind both.
2. Mechanism (0:30–2:30): whisking shears oil into tiny droplets; emulsifier molecules coat them so collisions do not merge.
3. Failure clinic (2:30–5:00): oil poured too fast, too-cold or too-warm ingredients — show the broken texture and why it happens.
4. Fix rule (5:00–6:30): restart with a fresh binder (yolk or mustard) and stream the broken batch back in slowly.
5. Label beat + recap card (6:30–8:00): reading emulsifiers and gums on dressing labels. Original narration only.
