How much ice is suggested for the Shaken Espresso?

For the Shaken Espresso, the suggestion of a heaping cup of ice indicates an ample amount, which is essential for achieving the desired temperature and dilution of the drink.

Using a heaping cup ensures enough ice is present during the shaking process to produce a smooth, vibrant beverage that maintains its chilled state until consumed.
