These days your rocks could be made from ice that was hand cut from a purified block of Icelandic spring runoff or crafted by purified filtration. But in all likelihood the ice you put in your cocktail was an afterthought pulled from the depths of a plastic bucket or freezer bin. But really, ice is the cornerstone of the perfect cocktail.

For those without Icelandic connections, ice has taken a turn for the better with Spirit Ice Vice, a wonderful gadget that makes your water rock solid round. Spirit Ice Vice provides you with a mold that once frozen is placed under a several pound slab of metal that, using the laws of gravity and thermal conductivity, creates a perfectly round ball of ice. Maximum cold for minimum surface area means that less water will melt into your single malt. Consider your ice cube evolved.
