What You Need to Know
Exploits chocolate's polymorphic crystallization (βV form stabilization at 27-28°C) to form rigid lamellae around embedded particulates. Feuilletine's wheat-based honeycomb structure provides fracture points for clean breakage.
Creates dramatic snap and multi-textural experience in plated desserts while protecting delicate inclusions from moisture migration.
