How do I clone a Lion disk?

Haven't come across this need until now but I used the latest "Lion-compatible" version of Superduper,and worked out that the recovery partition wasn't copied over.

The best way I can work out without anything particularly involved is to install Lion on the host disk (I have several of the USB sticks I bought for upgrading exisitng machines so it's not the ginormous pain it might otherwise have been), then use Superduper to clone the "Macintosh HD" partition. That's what I'm trying right now.

I can't seem to track down a one-hit solution. Is there one?
