Sounds like work...

If I'm inclined, I run it under the RO spigot for a few seconds until the cube breaks up. Otherwise, I put a piece on a spoon for about 5 minutes. Done - nicely thawed.
As for the juices, it has been debated whether or not they have some value. Were there any conclusions on this?
