Crystal clear ice spheres aren't just aesthetically pleasing in a cocktail glass; they're actually denser than conventional cubes, which means they melt slower. That means your favorite spirits stays perfectly chilled without getting too watered down too quickly. Just fill the four-sphere silicone tray, freeze, pop one in your glass, and enjoy.

• Makes four ice spheres
