What You Need to Know
Involves supersaturating a sugar solution (typically sucrose) that nucleates on food surfaces, forming microcrystals. May use seed crystals (ground sugar) or temperature shock to initiate crystallization. Distinction from caramelization (no browning reactions occur).
Creates a sparkling, frost-like appearance on fruits (e.g., grapes, citrus zest) or pastries (croissants, choux). Provides contrast to soft interiors. Professional kitchens often use isomalt blends for enhanced stability.
