Not a fan of ten tiny ice cubes in your drink. Why not use a King Cube, basically a large 2-inch square ice cube. The larger ice cubes will keep your drink colder longer, and can even be infused with flavors (or more booze) for some truly custom drinks.
The King Cube ice cube tray is made of food grade silicone and is easy to fill and extract frozen cubes from. Each silicone tray makes six large ice cubes.
