If you really want crystal clear ice cubes, boil the water first and let it cool before freezing.
I've never heard this before! It isn't a practical tip for daily use (especially if you go through ice cubes like we do!), but for entertaining this would be fun and add a little "something extra," don't you think?
I saw this in our local, weekly paper tucked among some ads at the bottom of the page!
I found this video looking for an image of clear ice. The maker advises two additional tips for achieving crystal clear ice (ignore the spelling and grammar errors). Very interesting!
