Description
A technique that layers cold butter within dough to create flaky, airy brioche.
Technical
The process relies on maintaining a temperature gradient—cold butter (32–35 °C) in a warm dough (18–22 °C)—to keep fat crystals solid yet pliable, allowing them to be folded into the gluten network. During chilling, the butter recrystallizes, forming distinct layers, while yeast fermentation generates CO₂ that expands the dough, producing a light crumb.
Science
Primary Reaction
Emulsification of butter fat droplets into the dough matrix and recrystallization during chilling
