Ganache Glaze

Ganache glaze is a fluid chocolate-and-cream emulsion poured or spread over cakes, tarts and pastries to create a smooth, glossy coating. It is usually thinner than a filling or truffle ganache so that it flows evenly over the surface and settles into a uniform layer.

Ingredients and consistency

A basic ganache glaze combines chocolate with hot cream. The proportion depends on the chocolate, the desired thickness and whether the glaze must remain soft, set firmly or be sliced cleanly. Glucose syrup, butter or another suitable ingredient may be added to influence shine, flexibility and mouthfeel. Dark, milk and white chocolate behave differently because their cocoa solids, sugar and fat contents vary.

How to prepare a smooth ganache glaze

1. Chop the chocolate finely and place it in a heatproof bowl.
2. Heat the cream until hot but not aggressively boiling, then pour it over the chocolate.
3. Allow it to stand briefly so the heat softens the chocolate.
4. Stir from the centre outward to form a smooth, glossy emulsion. Use an immersion blender if needed, keeping the head submerged to avoid incorporating air.
5. Allow the glaze to cool to a fluid working consistency before pouring or spreading it over the prepared pastry.

Uses in pastry

Ganache glaze is used on chocolate cakes, entremets, tarts, petits gâteaux and other desserts where a clean chocolate finish is desired. It may be poured over a chilled or appropriately prepared cake, or used as a thin coating between layers and on top of a pastry.

Common mistakes

Overheating can damage the emulsion or make the glaze too fluid. Incorporating air can leave bubbles or a pitted finish. Applying it too cold can create thick ridges, while applying it too hot can melt or soften the underlying preparation.

Chef’s tip: Test the glaze on the side of a cold bowl or a small sample before coating the finished cake. Work at a temperature and viscosity suited to the chocolate and the surface; a single temperature is not correct for every formula.

Key distinction: Ganache glaze is formulated to flow and coat. A thicker ganache is more suitable as a filling, piping preparation or truffle centre.
