How to Succeed with Mirror Glaze

Achieving a perfect mirror glaze requires attention to temperature, texture, and technique. Follow these key tips.

The Right Temperature is Key

. The glaze should be 38–40°C (100–104°F) before pouring
. If it is too hot, it will be too thin and run off the cake
. If it is too cold, it will be too thick and create lumps

Your Cake Must Be Frozen

. A mirror glaze works best on a cake that is rock-solid frozen
. This ensures the glaze sets quickly and stays smooth

Use a Stick Blender

. To prevent air bubbles, blend the glaze with an immersion blender
. Keep the blade under the surface while blending to avoid air pockets

One Pour, No Touch-Ups

. Pour the glaze in one smooth motion and do not go back to fix spots
. Too much handling can ruin the glossy effect

Save Leftover Glaze

. Extra glaze can be frozen and reused
. Reheat it to 38–40°C before using again

. 40g (⅓ cup) all-purpose flour
. A pinch of salt

Strawberry Mousse

. 200g (7 oz) strawberry purée (blended and strained strawberries)

Strawberry Mirror Glaze

. 100g (3.5 oz) white chocolate
. 75ml (⅓ cup) heavy cream
. 75g (⅓ cup) strawberry purée
. 75g (⅓ cup) sugar
. 1 tbsp glucose syrup (or corn syrup)
. 3 gelatin sheets (or 1 tsp powdered gelatin)

Instructions

Step 1: Make the Brownie Base

1. Preheat oven to 175°C (350°F). Grease and line an 18 cm (7-inch) round cake pan with parchment paper.
2. Melt butter and chocolate together over a double boiler or in the microwave in short intervals. Stir until smooth.
3. Remove from heat and whisk in sugar. Add eggs one at a time, mixing well.
4. Sift in flour and salt, then gently fold everything together.
5. Pour batter into the cake pan and bake for 20 minutes. The brownie should be set but still slightly fudgy. Let it cool completely.

Step 2: Prepare the Strawberry Mousse

1. Soak gelatin sheets in cold water for 10 minutes.
2. Heat half of the strawberry purée and sugar in a saucepan until warm. Remove from heat and stir in the softened gelatin until dissolved. Add the remaining purée and let it cool.
3. Lightly whip the heavy cream and mix it with the yogurt. Gently fold it into the strawberry mixture to create a smooth mousse.

Step 3: Assemble the Cake

1. Use a 20 cm (8-inch) silicone cake mold or a springform pan lined with acetate. Pour the mousse into the mold.
2. Let the mousse sit in the freezer for 5–10 minutes, then carefully press the cooled brownie base into the mousse.
3. Freeze the cake for at least 5–6 hours or overnight until completely firm.

Step 4: Make the Strawberry Mirror Glaze

1. Soak gelatin sheets in cold water for 10 minutes.
2. Finely chop white chocolate and place it in a tall mixing jug.
3. Heat heavy cream, strawberry purée, sugar, and glucose syrup in a saucepan until it starts to simmer. Remove from heat and stir in the gelatin until fully dissolved.
4. Pour the hot mixture over the white chocolate and blend with an immersion blender. Keep the blade under the surface to avoid air bubbles.
5. Let the glaze cool to 38–40°C (100–104°F) before pouring.

Step 5: Glazing the Cake

1. Remove the frozen cake from the mold and place it on a wire rack over a tray.
2. Pour the glaze over the frozen cake in a circular motion, ensuring even coverage.
3. Allow excess glaze to drip off for 2–3 minutes. Then, gently clean the edges with a spatula.
4. Transfer the cake to a serving plate and let it thaw in the refrigerator for 4–5 hours before serving.

Decorating Ideas

. Fresh strawberries and edible flowers for a natural look
. Chocolate decorations for an elegant touch
. Gold dust or sprinkles to enhance the presentation
