Ingredients

Why this recipe works

The method of pouring melted chocolate directly over broken biscuits ensures that every bite is perfectly coated, creating a cohesive block that holds together when sliced.

This approach allows the chocolate to permeate the crevices, providing a structural integrity that is both sturdy and easy to cut through.

Using a double boiler for melting chocolate prevents scorching, which is critical for maintaining the glossy finish of the glaze.

Controlling the temperature ensures the chocolate remains tempered enough to set firmly, providing that essential snap when the cake is sliced into individual portions.

Notes and substitutions

The choice of biscuits significantly impacts the final texture; a plain, crunchy variety works best to absorb the chocolate while maintaining a distinct bite. If using a softer biscuit, the cake may lose some of its characteristic crunch, so prioritize those with a firmer structure.

For the best results, use a high-quality chocolate with a cocoa content of at least 60 percent. This ensures the glaze is deep in flavor and sets with a professional, shiny finish that resists melting too quickly at room temperature.

• tea biscuits: Use digestive biscuits, graham crackers, or any plain, crunchy tea biscuit available in the pantry.
• dark chocolate: Semi-sweet chocolate chips provide a similar texture and richness for the glaze if preferred over dark chocolate.
