Description
Precision-controlled crystallization of cocoa butter enables liquid chocolate to form solid shells around viscous fillings.
Technical
Tempering induces beta-V cocoa butter crystallization (melting point 34-36°C) for snap and gloss. Ganache filling stability relies on emulsion breakdown prevention via 45-55% fat content and <0.6 water activity.
Culinary Significance
Allows creation of shelf-stable, bite-sized flavor delivery systems with contrasting textures between shell and filling.
