How do you make a chocolate showpiece shiny?

To make a chocolate showpiece shiny, you can polish it with ice water.

Here's how to achieve a shiny finish on your chocolate showpiece:

1. Prepare Ice Water: Make sure the ice water is very cold, aiming for a temperature around 4 degrees Celsius.
2. Apply with a Fiber Cloth: Use a clean fiber cloth, dampen it with the ice water, and gently polish the surface of the chocolate. Work quickly.

The cold water helps to slightly melt and then re-solidify the surface of the chocolate, creating a smooth and shiny appearance.
