What You Need to Know
The glaze relies on the gelling properties of gelatin (collagen hydrolysate) and the Maillard reaction for depth. The reflective surface is achieved through precise sugar concentration (65-75°Brix) and smooth gel formation. Common variants include chocolate mirror glaze (with cocoa solids) and fruit-based versions with pectin adjustments.
Used primarily in pastry for entremets and plated desserts, mirror glaze creates a visually striking, glass-like finish. It requires careful temperature control (32-35°C for application) and is often layered over mousse cakes. Savory applications include glazing terrines or foie gras with reduced stock-based versions.
