Based on the provided video excerpt, the specific method of attaching chocolate spheres to a cake isn't detailed, but the video implies creating a visual effect like a "blue garland or a balloon arch" using varying sizes of chocolate spheres. Therefore, the assumption is that the spheres are attached to the top of the cake in an arch-like manner. Here's a general approach based on common cake decorating techniques:
-
Prepare the Spheres: Ensure the chocolate spheres are made and are of the desired size and color (the video references different sizes).
-
Prepare the Cake: The cake should be frosted with a stable frosting like buttercream or ganache. This will provide a surface for the spheres to adhere to.
-
Adhesive: Use a small amount of melted chocolate or buttercream frosting as "glue" to attach the spheres. Melted chocolate will harden and create a strong bond, while buttercream allows for more flexibility if you need to reposition the spheres.
-
Placement: Starting with the largest spheres (if following the "balloon arch" visual), attach them strategically along the top edge of the cake. Gradually add smaller spheres to fill in the gaps and create the desired garland or arch shape. The video suggests using a gradient, going from lightest to darkest.
-
Support (If Needed): For larger or heavier spheres, especially if creating a significant arch, consider using hidden supports like toothpicks or skewers inserted into the cake to provide extra stability. These should be completely concealed by the chocolate spheres.
Example Approach for a "Balloon Arch" Design:
- Base: Place the largest spheres at the base of the arch, using melted chocolate to secure them to the frosted cake.
- Arch Formation: Gradually decrease the size of the spheres as you move upwards and inwards to create the arch.
- Securing: Hold each sphere in place for a few seconds while the melted chocolate begins to set.
- Filling: Use smaller spheres to fill in any gaps and create a seamless transition between the larger spheres.
Important Considerations:
- Temperature: Work in a cool environment to prevent the chocolate from melting too quickly.
- Quantity: Make extra spheres in case of breakage or the need for adjustments.
- Weight Distribution: Ensure the weight of the spheres is evenly distributed to prevent the cake from tilting or collapsing.
