Description
Manual tempering method inducing stable cocoa butter crystallization through controlled cooling.
Technical
Involves spreading molten chocolate on a marble slab to promote nucleation of Form V beta crystals (melting point 34-35°C) while avoiding unstable Form IV. Shear forces from spreading align triglycerides (POP, POS, SOS) for snap and gloss.
Culinary Significance
Essential for creating chocolate with proper snap, sheen, and heat resistance in artisanal applications where machines aren't available.
