Know what hurts? Watching a lowball of rare, delicious whiskey go watery and limp thanks to those half-moons of ice your freezer churns out. Upgrade your ice with Tovolo King Cube 2×2 Ice Cube Trays ($10 each). Start making real cubes–fat, sturdy, slow-melting square blocks that cool a drink without neutering it. A couple of these trays would make a great gift for a fine whiskey or scotch drinker.
