What You Need to Know
Starch gelatinization occurs at 60-70°C as water hydrates flour granules, while egg proteins (ovalbumin, ovotransferrin) denature at 62-65°C to form a protein network. Steam expansion during baking (100-180°C) creates hollow interiors via vapor pressure.
The unique ability to puff without chemical leaveners makes choux indispensable for airy pastries. Proper hydration and emulsification determine structural integrity - undercooked paste collapses, while overworked eggs yield dense textures.
