From large spheres and perfect cubes to unique shapes that liven things up, many cocktails are best enjoyed with the proper ice to liquid ratio. If you've ever been to an upscale craft cocktail bar, you've seen this theory in practice when the bartender pulls out unusually large cubes or spheres of ice that seem to fill up the entire rocks glass. That's because the problem with traditional ice cubes–whether straight from your freezer or an industrial ice machine–is they're usually lacking in surface area and small enough to melt quickly, thus diluting the contents of your drink. Larger ice molds that create spheres, cubes, and other shapes have more surface area and density, so they retain their shape and temperature for longer, making them the perfect companion for many drinks. So, if you want to take your at-home cocktail making game up a notch, it makes sense to have a quality ice mold ready in your freezer for creating impressive, bar-quality drinks anytime.
