Mastering Mirror Glaze: The Science Behind the Shine

Mirror glaze is one of the most spectacular finishes in modern pastry. But behind this perfect shine lies a precise science that few courses teach in detail.

The Basic Formula

A mirror glaze relies on 5 ingredients: water, sugar, glucose, sweetened condensed milk, and gelatin. White chocolate or couverture chocolate provides the shine and texture.

The Critical Temperature: 30-35°C

This is THE determining factor. Below 30°C, the glaze sets too quickly and creates marks. Above 35°C, it runs off without adhering. Use a laser thermometer for precise control.

Eliminating Air Bubbles

Bubbles are the #1 enemy of shine. Three techniques to eliminate them:

• ◆Blend with a hand blender without incorporating air
• ◆Wrap in cling film in contact with the surface during cooling
• ◆Pass the glaze through a fine sieve before use

The Entremet at -18°C

Your entremet MUST be frozen to at least -18°C before glazing. The temperature difference between the glaze (32°C) and the entremet (-18°C) is what creates the instant solidification and the mirror effect.

Our Masterclass "Engineering & Architecture of Modern Entremets" devotes an entire section to mirror glazing, with hands-on practice on 8 different entremets.
